Zinc linked amino acid complex, Zn(l-proline)(2), is considered as a green catalyst for the synthesis of novel series of pyrimidine derivatives 5a-q. The pyrimidines 5a-q were prepared via two pathways: the first is a one-pot reaction of guanidines 3(a-c) with aromatic aldehyde 1 and acetophenones 2; and the second one is the reaction of guanidines 3(a-c) with different chalcones 4(a-j) in aqueous medium. The simplicity of the operation, the short reaction time, and the high efficiency (97%) are the main advantages of this protocol. Furthermore, the green aspects of this synthetic protocol were further investigated by examining the reusability of Zn(l-proline)(2) complex throughout five consecutive cycles without a significant loss of catalytic activity. This new procedure has presented remarkable advantages in terms of safety, simplicity, stability, mild conditions, a short reaction time, excellent yields, and high purities without using any organic solvents.

Simple alpha-(bromomethyl)styrenes can be processed to a variety of 1,1-difluorinated electrophilic building blocks via I(I)/I(III) catalysis. This inexpensive main group catalysis strategy employs p-TolI as an effective organocatalyst when combined with Selectfluor (R) and simple amine center dot HF complexes. Modulating Bronsted acidity enables simultaneous geminal and vicinal difluorination to occur, thereby providing a platform to generate multiply fluorinated scaffolds for further downstream derivatization. The method facilitates access to a tetrafluorinated API candidate for the treatment of amyotrophic lateral sclerosis. Preliminary validation of an enantioselective process is disclosed to access alpha-phenyl-beta-difluoro-gamma-bromo/chloro esters.

The kinetics of intramolecular-contact formation between remote functional groups in peptides with restricted conformational flexibility were examined using designed peptides with variable-length proline bridges. As probes for this motion, free radicals were produced using the center dot OH-induced oxidation at the C-terminal methionine residue of gamma-Glu-(Pro)(n)-Met peptides (n = 0-3). The progress of the radicals’ motion along the proline bridges was monitored as the radicals underwent reactions along the peptides’ backbones. Of particular interest was the reaction between the sulfur atom located in the side chain of the oxidized Met residue and the unprotonated amino group of the glutamic acid moiety. Interactions between them were probed by the radiation-chemical yields (expressed as G values) of the formation of C-centered, alpha-aminoalkyl radicals (alpha N) on the Glu residue. These radicals were monitored directly or via their reaction with p-nitroacetophenone (PNAP) to generate the optically detected PNAP(center dot-) radical anions. The yields of these alpha N radicals were found to be linearly dependent on the number of Pro residues. A constant decrease by 0.09 mu M J(-1) per spacing Pro residue of the radiation-chemical yields of G(alpha N) was observed. Previous reports support the conclusion that the alpha N radicals in these cases would have to result from (S.*.N)(+)-bonded cyclic radical cations that arose as a result from direct contact between the ends of the peptides. Furthermore, by analogy with the rate constants for the formation of intramolecularly (S.*.S)(+)-bonded radical cations in Met-(Pro)-Met peptides (J. Phys. Chem. B 2016, 120, 9732), the rate constants for the formation of intramolecularly (S.*.N)(+)-bonded radical cations are activated to the same extent for all of the gamma-Glu-(Pro)(n)-Met peptides. Thus, the continuous decrease of G(alpha N) with the number of Pro residues (from 0 to 3) suggests that the formation of a contact between the S-atom in the C-terminal Met residue and the N-atom of a deprotonated N-terminal amino group of Glu is controlled in peptides with 0 to 3 Pro residues by the relative diffusion of the S center dot+ and unoxidized N-atom. The overall rate constants of cyclization to form the (S.*.N)-bonded radical cations were estimated to be 3.8 X 10(6) , 1.8 x 10(6) , and 8.1 x 10(5) s(-1) for peptides with n = 0, 1, and 2 Pro residues, respectively. If activation is the same for all of the peptides, then these rate constants are a direct indication for the end-to-end dynamics along the chain.

Cyclization of tosylmethyl isocyanide with alpha-oxodithioesters in the presence of KOH is reported for the synthesis of 4-methylthio-5-acylthiazoles. Similarly, ethyl isocyanoacetate underwent cyclization with alpha-oxodithioesters to form 4-ethoxycarbonyl-5-acylthiazoles in the presence of DBU/EtOH. Mechanisms for the formation of thiazoles are proposed. These thiazoles can also be obtained by Takeda reaction, in which thiazole-4,5-anhydride is acylated with aromatic compounds followed by esterification; however, that approach requires two steps and suffers from the formation of a regioisomeric mixture of products.

Hollow magnetic nanoparticles (MNPs) with tetrahedral morphology were synthesized and then covered by a shell prepared by coating with melamine-formaldehyde followed by the introduction of glucose-derived carbon. Subsequently, Pd nanoparticles were immobilized and the core-shell nanocomposite was carbonized. The obtained magnetic catalyst was successfully applied for the hydrogenation of nitroarenes in aqueous media. To investigate the effects of the morphology of MNPs, the nature of carbon shell, and the order of incorporation of Pd nanoparticles, several control catalysts, including the MNPs with different morphologies (disc-like and cylinder); MNPs coated with different shells (sole glucose-derived carbon or melamine-formaldehyde carbon shell); and a nanocomposite, in which Pd was immobilized after carbonization, were prepared and examined as catalyst for the model reaction. To justify the observed different catalytic activities of the catalysts, their Pd loadings, leaching, and specific surface areas were compared. The results confirmed that tetrahedral MNPs coated with porous N-rich carbon shell exhibited the best catalytic activity. The high catalytic activity of this catalyst was attributed to its high surface area and the interaction of N-rich shell with Pd nanoparticles that led to the higher Pd loading and suppressed Pd leaching.

The extensive use of antimicrobial drugs and their resistance against bacterial infections have led to discover new antimicrobial compounds. In this study, we wish to report, one-pot synthesis of 2-amino-3-cyanopyridine derivatives (1a-14a). These compounds were synthesized in the presence of Cu(OAc)(2) as a highly effective heterogeneous acid catalyst. Here we evaluated the antimicrobial activities of these compounds against different species of microorganisms including gram positive and gram negative bacteria as well as fungi. Standard antimicrobial methods include disc diffusion and Broth microdilution method according to the protocol of the Clinical and Laboratory Standards Institute (CLSI). Synthesis of 2-amino-3-cyanopyridine derivatives were done via reaction of aromatic aldehydes, acetophenone derivatives, malononitrile and ammonium acetate in the presence of Cu(OAc)(2) under reflux condition. The results show compound 2-amino-6-(4-chlorophenyl)-4-phenylnicotinonitrile (10a) had the best antimicrobial efficacy toward C. albicans, E. faecalis, P. aeroginosa and E. coli. In conclusion, comparing the structure and activity of the compounds (10a), this compound with the presence of Cl residue atpara-position of phenyl ring improves the antibacterial and antifungal activity.

Liver cancer is one of the most important cancers that easily affects many organs in the body. Valproate is a well-known branched fatty acid and is commonly used as an antiepileptic in liver cancer therapy. Similar to many drugs, this chemical drug can induce fulminant liver failure in patients with liver cancer. So, finding new therapeutic agents with fewer side effects is of great attention. This study explains synthesis and characterization of a new effective nanocatalyst ZnO@SiO2-NH2, which can be a suitable candidate for valproate. The prepared nanocatalyst was characterized by FT-IR, TEM, XRD and FE-SEM and formation of the desired nanoparticles with a medium grain size of 70-90 nm is justified. Then, the synthesized nanocatalyst is checked in the multi-component synthesis of some important model drugs involving substituted 2-aminothiophenes, as effective compounds against human liver cancer. The present methodology showed good generality and wide scope, nearly short span of time, good yield, easy workup and environmental friendly conditions for the preparation of the target compounds. At the final part of this study, the in vitro cytotoxicity potential of the prepared nanoparticle is investigated against a well-known human cancer cell line HepG2 via the MTT assay. The experiments reveal that ZnO@SiO2-NH2 nanoparticles have significant cytotoxicity towards the selected cell line. As a result, although ZnO@SiO2-NH2 can be used to treat liver cancer cells, however, this nanoparticle can be utilized to synthesize 2-aminothiophenes, as effective anti-liver cancer drugs like valproate.

An efficient Ni(ClO4)(2)center dot 6H(2)O-promoted amidoalkylation re-action for the synthesis of 3-substituted isoindolinones involving various gamma-hydroxy lactams and nucleophiles has been successfully developed. The transformation proceeds with both carbon (ketones and arenes) and heteroatom (alcohols, thiols, and amines) nucleophiles and in both intermolecular and intramolecular manners. The prominent features of the present strategy are wide substrate scope, excellent group tolerability, and moderate to good yields (up to 96% yield). The present strategy is also characterized by remarkable superiority over the current synthetic methods. Furthermore, the reaction could be scaled up to the multigram scale.
