The stereoselective synthesis of 3,3 ‘-disubstituted oxindoles having all-carbon quaternary stereocenters has been achieved using KOH as a base with an excellent diastereomeric ratio (98 : 2). The practicability of the present methodology has been validated with the synthesis of a series of substrates in good to excellent yields. The aesthetic simplicity, accessibility, and eco-friendly base (KOH) have prompted the broader application of the present methodology in organic synthesis.

I found the field of Chemistry; Crystallography very interesting. Saw the article A Simple Strategy for Fabrication of In(OH)(3)/ZnIn2S4 Heterostructure as Visible- light-driven Photocatalyst for Selective Oxidation published in 2019.0. Product Details of 100-51-6, Reprint Addresses Chen, ZX (corresponding author), Fuzhou Univ, Instrumental Measurement & Anal Ctr, Fuzhou 350116, Fujian, Peoples R China.; Chen, ZX (corresponding author), Fuzhou Univ, Coll Chem, State Key Lab Photocatalysis Energy & Environm, Fuzhou 350116, Fujian, Peoples R China.; Chen, ZX (corresponding author), Fujian Prov Univ, Key Lab Ecol Environm & Informat Atlas, Fuzhou 351100, Fujian, Peoples R China..

The cubic In(OH)(3)/ZnIn2S4 heterostructures were successfully synthesized via a simple strategy of post-treatment of cubic ZnIn2S4 (C-ZIS), and their structures and properties were characterized by X-ray diffraction (XRD), UV-vis diffuse reflectance spectra (DRS), field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM). According to the results, the tofu-like In(OH)(3) semiconductor as a new crystal phase appeared in the matrix of C-ZIS and formed a In(OH)(3)/ZnIn2S4 heterostructure. Compared with pure C-ZIS, the heterostructure exhibits higher photocatalytic activity towards selective oxidation of benzyl alcohol under visible light. The In(OH)(3) /ZnIn2S4 heterostructure manifests the best and the highest photocatalytic performance via 18 h post-treatment, which achieved nearly 100% selectivity, 35.5% conversion and 34.5% yield. This is ascribed to the formation of In(OH)(3)/ZnIn2S4 heterostructure to promote the transfer of photogenerated electron-hole pairs and thus efficiently inhibits their recombination, leading to the longer lifetime of photo-induced carriers. Furthermore, a possible photocatalytic mechanism is proposed and discussed. Our current work could boost more interest in researching the semiconductor materials of ternary chalcogenides and enlarging the applications based on cubic ZnIn2S4 heterostructure as visible-light-driven photocatalyst.

Using the oxidized, carboxylic acid-containing form of MPEG-750, esterification with racemic vitamin E affords a new surfactant (TPG-lite) that functions as an enabling, nanoreactor-forming amphiphile for use in many types of important reactions in synthesis. The presence of a single ester bond is suggestive of simplified treatment as a component of (eventual) reaction waste water, after recycling. Many types of reactions, including aminations, Suzuki-Miyaura, SNAr, and several others are compared directly with TPGS-750-M, leading to the conclusion that TPG-lite can function as an equivalent nanomicelle-forming surfactant in water. Prima facie evidence amassed via DLS and cryo-TEM analyses support these experimental observations. In silico evaluations of the aquatic toxicity and carcinogenicity of TPG-lite indicate that it is safe to use. (C) 2021 Elsevier Ltd. All rights reserved.

The dimeric lindenane sesquiterpenoids are mainly isolated from the plants of Chloranthaceae family. Structurally, they have a crowded molecular scaffold decorated with more than 11 stereogenic centers. Here we report divergent syntheses of eight dimeric lindenane sesquiterpenoids, shizukaols A, C, D, I, chlorajaponilide C, multistalide B, sarcandrolide J and sarglabolide I. In particular, we present a unified dimerization strategy utilizing a basemediated thermal [4 + 2] cycloaddition between a common furyl diene, generated in situ, and various types of dienophiles. Accordingly, all the three types of lindenane [4 + 2] dimers with versatile biological activities are accessible, which would stimulate future probing of their pharmaceutical potential.

In the enantioselecitve hydrogenation of (E)-2-methyl-2-butenoic acid (1) over a cinchonidine-modified Pd/C catalyst, the addition of hydrogen preferentially proceeds from the Re-Si enantioface of the C=C double bond of 1 to yield (S)-2-methylbutanoic acid ((S)-3). Double bond migration of 1 takes place under the reaction conditions and is followed by immediate hydrogenation to yield 3 in a poor enantiomeric purity. Deuterium labeling experiments at 0.1 MPa and 1.9 MPa of D-2 verified the previous assumption of competitive double bond migration. The combination of isotopic labeling experiments and chiral analysis revealed that the double bond migration of 1 proceeds with the same enantiofacial differentiation as the hydrogenation of 1. Thus, interaction of 1 with cinchonidine adsorbed on the Pd surface may control the configuration of the double bond migration and the hydrogenation.

Ten new pyridine linked various substituted thiazole hybrids through (hydrazonomethyl) phenoxy-acetamide spacer were synthesized. The synthetic strategy was based on the reaction of the precursor 2-(4-((2-carbamothioylhydrazono)methyl)phenoxy)-N-(pyridin-2-yl)acetamide (3) with various alpha-halogenated carbonyl compounds (namely; phenacyl bromides, ethyl bromoacetate, diethyl bromomalonate and 3-chloropentane-2,4-dione). Moreover, the cytotoxicity properties of the synthesized compounds have been studied against liver carcinoma (HepG2), laryngeal carcinoma (Hep-2), prostate cancer (PC3), breast cancer (MCF-7) and normal fibroblast cells (W138). The pyridine-thiazole compounds 7 and 10 revealed promising anticancer activity against MCF-7 and HepG2 cell lines with IC50 values in the range 5.36-8.76 mu M compared to the activity of 5-fluorouracil. Docking study provided valuable insights for binding sites of the synthesized compounds with Rho-associated protein kinase (ROCK-1). (C) 2020 The Authors.

A new method for the fast synthesis of diverse 4-aryl-6-cycloamino-1,3,5-triazin-2-amines was developed. The synthesis is performed under microwave irradiation in a one-pot manner from cyanoguanidine, aromatic aldehydes, and cyclic amines. Their three-component reaction in the presence of hydrochloric acid produced dihydrotriazines, which were then converted (without isolation) into the targeted compounds via aromatic dehydrogenation in the presence of alkali. The reaction tolerated various aromatic aldehydes (including heterocyclic) and cyclic amities. Crystal structures of two representative 4-aryl-6-morpholino-1,3,5-triazin-2-amines were established by X-ray crystallography. The results of preliminary biological screening identified potent antileukemic activity for 6-[3,4-dihydroisoquinolin-2(1H)-yl]-4- phenyl-1,3,5-triazin-2-amine.

For decades the steric effect was still ambiguously understood in catalytic benzylation reactions of arenes with benzyl alcohol, which limited the green synthesis of phenylmethane derivates in industrial scale. This research applies a series of silica-alumina beta zeolites to systematically evaluate factors like catalyst porosity, reactants molecule size, and reaction temperature on catalytic benzylation. First, a suitable hierarchical beta zeolite catalyst was screened out by X-ray powder diffraction, N-2 adsorption-desorption, and probe benzylation with p-xylene. In the following substrates expanding study, for a typical benzylation of benzene, it showed extraordinary performance among literature reported ones that the conversion was 98% while selectivity was 90% at 353 K only after 10 min. The steric effect of aromatics with different molecular sizes on benzylation was observed. The reaction activities of four different aromatics followed the order: benzene > toluene > p-xylene > mesitylene. Combined with macroscopic kinetic analysis, this comprehensive study points out for the first time that the nature of this steric effect was dominated by the relative adsorption efficiency of different guest aromatic molecules on the host zeolite surface.
