Mizoroki-heck reactions with 4-phenoldiazonium salts

Significantly better yields were achieved in Mizoroki-Heck reactions using 4-phenoldiazonium salts instead of their O-alkylated analogues under otherwise identical conditions. We found that a one-flask deacetylation-diazotation- precipitation sequence starting from paracetamol or acetanilides derived thereof provides a convenient access to the required diazonium tetrafluoroborates. The utility of these arylating agents in palladium-catalyzed C-C bond forming reactions was demonstrated for a one-flask-synthesis of the heterocyclic core of the drug aripiprazole. Notably, the diazonium salt formation from an acetanilide could be combined with two Pd-catalyzed steps in a one-flask sequence, without any exchange of solvents or isolation of intermediates.

Fluorinated phosphonate analogues of phenylalanine: Synthesis, X-ray and DFT studies

Due to their biological activity and structural analogy to corresponding alpha-amino acids, alpha-aminophosphonates and their fluorinated derivatives provide an important source for drug discovery. Therefore convenient access to this class of compounds is still desirable. Four series of novel phosphonate analogues of fluorinated phenylalanine containing variable number of fluorine atoms in different positions of the phenyl ring were synthesized and subjected to solid state characterization by single-crystal X-ray diffraction analysis, and to studies with the use of NMR, HRMS and DFT methods. Such an approach provided valuable information in regard to preferable conformation, hydrogen bonds and also weak intermolecular interactions present in the crystals investigated. As analogues of naturally occurring compounds, the obtained alpha-aminophosphonates have a big potential for biological activity. Formation of some indolinylphosphonates as minor products arisen from intramolecular SNAr reactions show that aminophosphonates exhibiting an electronically depleted aromatic group, and possessing a fluorine atom in ortho position of the phosphonoalkyl substituent may give an entrance to further derivatives that may exhibit entirely new properties.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 214894-89-0 is helpful to your research. Reference of 214894-89-0

A short entry to enantiopure 2-substituted 1,4-benzodioxanes by efficient resolution methods

(R)-1,4-Benzodioxane-2-carboxilic acid (R)-1 was obtained by resolution of the racemic acid 1 with stoichiometric or nonstoichiometric (+)- dehydroabietylamine (+)-2 in high chemical yield and enantiomeric excess. (S)-1 was isolated from the mother liquors of the crystallisation of (R)-1¡¤(+)-2 and its enantiomeric excess maximised by recrystallisation procedures involving a precipitation under kinetic control or, alternatively, by conversion into the methyl ester followed by a single crystallisation. The different mechanisms of the two S enrichments is well explained by the binary phase diagrams of the acid and of the ester, which show that the former is a racemic compound, whereas the latter a conglomerate. The DSC analyses were extended to 2-hydroxymethyl- and 2-mesyloxymethyl-1,4-benzodioxane, establishing that the alcohol forms a racemic compound, while its mesyl ester a conglomerate. On the basis of these results, different resolution strategies can be designed to obtain useful homochiral 2-substituted 1,4-benzodioxanes coupling the resolution of 1 via diastereomeric salt formation with the enantiomeric enrichments by recrystallisations, preferably of its conglomerate forming derivatives.

Synthesis, structure-activity relationships, and anticonvulsant activities of 2-amino-4H-pyrido[3,2-e][1,3]thiazin-4-one derivatives as orally active AMPA receptor antagonists

As part of a program aimed at discovering orally active 2-amino-3-(3-hydroxy-5-methyl-4-isoxazolyl)propionic acid (AMPA) receptor antagonists, we screened our compound library and identified 2-[allyl(4-methylphenyl)amino]-4H-pyrido[3,2-e][1,3]thiazin-4-one (7) as a lead compound that inhibited kainate-induced neurotoxicity mediated by AMPA receptors in rat hippocampal cultures. Structure-activity relationship studies of a series of 2-amino-4H-pyrido[3,2-e][1,3]thiazin-4-one derivatives revealed that substituents on the phenyl ring attached to the 2-amino group and the 4H-pyrido[3,2-e][1,3]thiazin-4-one ring system play an important role in inhibitory activity against kainate-induced neurotoxicity. Several analogs bearing a phenyl group with a 4-substituent or five- or six-membered ring fused at the 3,4-positions exhibited potent inhibitory activity against kainate-induced neurotoxicity. Further, some of these compounds exhibited significant suppression of maximal electroshock seizure in mice following oral administration. Of these compounds, 2-[(4-chlorophenyl)(methyl)amino]-4H-pyrido[3,2-e][1,3]thiazin-4-one (16i) (YM928) demonstrated the most potent inhibitory effect with an ED50 value of 7.4mg/kg.

Novel 5-arylcarbamoyl-2-methylisoxazolidin-3-yl-3-phosphonates as nucleotide analogues

A series of 5-substituted 3-phosphonylated isoxazolidines have been obtained via cycloaddition of N-methyl-C-(diethoxyphosphoryl)nitrone with N-heteroaromatic acrylamides. Good trans/cis diastereoselectivities (d.e. 58-76%) of isomeric (3-diethoxyphosphoryl)isoxazolidines were observed. cis-and trans-Isoxazolidine phosphonates were evaluated for their antiviral activity against a broad range of DNA and RNA viruses but were found inactive. Their cytostatic activity toward L1210, CEM, and HeLa cells was also established, and compounds cis-12r and trans-11r having a 2,2-difluorobenzo[d][1,3]dioxole moiety slightly inhibited proliferation of HeLa cells at IC50 values of 186 and 179 M, respectively.

Synthesis of some 1, 4-benzodioxane containing methanesulfonamides and their hemolytic study on human blood

The aim of this work was to synthesize some methanesulfonamides bearing 1, 4- benzodioxane moiety and to evaluate their cytotoxicity profile through hemolytic study. The synthetic methodology involved the reaction of 1, 4-benzodioxane-6-amine (1) with methanesulfonyl chloride (2) in aqueous alkaline medium under stirring for 2-3 hours and dynamic pH control at 9 to form N-(2, 3-dihydrobenzo[1, 4]dioxin-6-yl)methanesulfonamide (3). The synthesized sulfonamide, 3, was dissolved in DMF and LiH was added as an activator. Then, it was stirred for 2-3 hours with a series of aralkyl/alkyl halides, 4a-g, to yield N-alkyl/ aralkyl-N-(2, 3-dihydrobenzo[1, 4]dioxin-6- yl)methanesulfonamides (5a-g). The structural analysis of the derivatives was performed by FT-IR, 1H-NMR and EI-MS. When these molecules were evaluated for their hemolytic study, the molecule 5g was found to be least toxic amongst the series. Hence, this molecule might be utilized as safe therapeutic agent.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C8H9NO2, you can also check out more blogs about22013-33-8
