Herein, we describe the formation of quaternary carbon centers with excellent diastereoselectivity via a strain-release protocol. An organometallic species is generated by Cp*Rh(III)-catalyzed C-H activation, which is then coupled with strained bicyclobutanes (BCBs) and a prochiral carbon electrophile in a three-component reaction. This work illustrates a rare example of BCBs in transition metal catalysis and demonstrates their broad potential to access novel reaction pathways. The method developed exhibits ample functional group tolerance, and the products can be further transformed into valuable alpha-quaternary beta-lactones. Preliminary mechanistic investigations suggest a twofold C-C bond cleavage sequence involving sigma-bond insertion and an ensuing beta-carbon elimination event.

We demonstrate a method to boost the photocatalysis of titania by constructing a core-shell structure. The crucial technique is to capsulate the titania nanoparticles by a sheath of nitrogen-doped carbon (TiO2@N-AC) with a thickness at 3.5-7.5 nm, which creates an exceptional effect to accelerate the catalytic hydrogenation of substituted nitroarenes with isopropanol as the hydrogen source under ultraviolet or visible-light irradiation. In the catalytic hydrogenation of various nitroarenes with substituted groups of -Cl, -F, -C-C, -C-O, and -C=N, TiO2@N-AC exhibits high conversions and selectivities to the corresponding functionalized anilines, even outperforming the catalysts containing noble metals. Mechanism study demonstrates that the TiO2@N-AC catalyst benefits the selective adsorption of the nitro group rather than other substituted groups, which efficiently avoids the undesirable side reactions. Importantly, the catalyst is stable and exhibits constant performances in the continuous recycling tests.

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.

We report the one-pot synthesis of 2,2-disubstituted chromanes with electron-withdrawing substituents. This reaction provides a simple yet efficient route to a wide range of electron-deficient chromanes in high yield and excellent regioselectivity. The reaction of salicylaldehyde with 1,1-disubstituted ethylenes smoothly furnishes these electron-deficient chromanes, which can be further transformed into functionalized chromanes or chromene. For example, BW683C was effectively synthesized from 5-chlorosalicylaldehyde with 4-chlorostyrene in two steps in excellent yield. The present reaction thus provides versatile access to functionalized electron-deficient chromanes and chromenes and therefore constitutes a promising tool for the synthesis of biologically and photochemically active molecules.

In this contribution a physicochemical, IR and Raman characterization for the tin(ii) chloride dihydrate/choline chloride eutectic mixture is reported. The redox properties of this solvent were also studied by cyclic voltammetry finding that it can be successfully used as an electrochemical solvent for electrosynthesis and electroanalytical processes and does not require negative potentials as verified by the reduction of nitrobenzene. The potential use of this eutectic mixture as a redox solvent was further explored in obtaining aromatic amines and N-arylacetamides starting from a wide variety of nitroaromatic compounds. In addition, a fast synthetic strategy for the construction of a series of indolo(pyrrolo)[1,2-a]quinoxalines was developed by reacting 1-(2-nitrophenyl)-1H-indole(pyrrole) with aldehydes. This simple protocol offers a straightforward method for the construction of the target quinoxalines in short reaction times and high yields where the key step involves a tandem one-pot reductive cyclization-oxidation.

Category: benzodioxans. I found the field of Chemistry very interesting. Saw the article Synthesis and Herbicidal Activities of Novel Substituted Acetophenone Oxime Esters of Pyrithiobac published in 2020.0, Reprint Addresses Hu, H; Xu, DF (corresponding author), Changzhou Univ, Natl & Local Joint Engn Res Ctr High Efficiency R, Sch Pharmaceut & Life Sci, Changzhou 213164, Peoples R China..

A series of substituted acetophenone oxime esters of Pyrithiobac were synthesized as potential herbicides. The structures of the synthesized new compounds were confirmed by H-1 NMR, C-13 NMR, HRMS, and X-ray single-crystal diffraction (XRD). The pre-emergence and post-emergence herbicidal activity studies show that 4-CF3 (6 f), 4-NO2 (6 i), 4-NH2 (6 j), 4-F (6 l), and 2,4-2OCH(3) (6 s) substituted acetophenone oxime esters of Pyrithiobac exhibit better pre-emergence and post-emergence herbicidal activities against monocotyledon and dicotyledon weeds than other synthesized new compounds. In pre-emergence herbicidal activity study, 6 f, 6 i, 6 j, 6 l, and 6 s exhibit similar herbicidal activities against monocotyledon and dicotyledon weeds as compared to Staple (Pyrithiobac-sodium). In post-emergence herbicidal activity study, 6 f, 6 i, 6 j, 6 l, and 6 s exhibit similar herbicidal activities against dicotyledon weeds and better herbicidal activities against monocotyledon weeds as compared to Staple. Compounds 6 i and 6 l with high herbicidal activities and similar binding mode with acetolactate synthase as compared to Staple were further subjected to crop safety study. The results show that the safety of compound 6 l to cotton is as good as Staple and better than 6 i. The present work indicates that compound 6 l may serve as a new candidate for potential herbicides.

The first sequentially combined inorganic base promoted N-addition/[2,3]-sigmatropic rearrangement reaction of alpha-alkylidene pyrazolinones and propargyl sulfonium salts has been reported to construct homoallyl sulfur-containing pyrazolones with moderate to excellent yields. alpha-Alkylidene pyrazolinones function as N-nucleophilic agents distinguished from the reported C-addition reactions. Propargyl sulfonium salts were first involved in the [2,3]-sigmatropic rearrangement protocol differentiated from the well-established annulation reactions. The excellent regioselectivity, the broad scope of substrates, gram-scale synthesis and convenient transformation embody the synthetic superiority of this cascade process.

Designing and fabricating catalysts with highly dispersed metal nanoclusters (NCs) is very crucial for achieving high activity and selectivity. In this work, all-alkynyl-protected [Ag-74(C CPh)(44)](NO3)(2) cluster (Ag duster) with a well-defined structure was firstly intercalated in alpha-zirconium phosphate (alpha-ZrP) through ion-exchange. Then the atomically precise Ag cluster can be immobilized robustly in the support by a sequential process of carbonization, calcination and reduction. The supported Ag duster showed the relatively high catalytic activity (TOP = 222.9-445.8 h(-1)) and excellent recyclability for hydrogenation of a variety of nitroaromatics, as well as the compounds with carbon-carbon double bonds even if the loading of Ag was as low as 0.72 wt.%. Zirconium pyrophosphate acts as not only a stabilizer of Ag duster through a spatial confinement, but also an adsorption site for nitroaromatics. The residual carbon arisen from thermal decomposition of all-alkynyl ligand coordinating on Ag cluster exerted an important role in protecting Ag duster from sintering. As a result, the intercalation of Ag cluster in the interlayer region is a promising strategy for extending their potential applications in catalysis.
