An interestingcyclization reactions of aryl ketones with 2-amino aniline derivatives under SeO2 (oxidant) are described for the synthesis of benzoxazole, benzothiazole, benzimidazole and quinazolinone through the C-C cleavage of acetophenone. The reaction likely involves sequential C-N, C-O and C-S bond formation followed by C(CO)-C(alkyl) bond cleavage. Various substituted fused heterocycles are obtained in good to excellent (gram scale) yields in a single step from readily available acetophenones.

Two cis-1,2-diol-type chiral ligands (T-1 and T-2) and their tri-coordinated chiral dioxaborinane (T(1-2)B(1-2)) and four-coordinated chiral dioxaborinane adducts with 4-tert-butyl pyridine sustained by N -> B dative bonds (T(1-2)B(1-2)-N) were synthesized and characterized by various spectroscopic techniques such as NMR (H-1, C-13, and B-11), FT-IR and UV-Vis spectroscopy, LC-MS/MS, and elemental analysis. It was suggested that both ferrocene and trifluoromethyl groups played key roles in the catalytic and biological studies because they could tune the solubility of the chiral dioxaborinane complexes and adjust the strength of intermolecular interactions. To assess the biological activities of newly synthesized chiral dioxaborinane compounds, DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging, reducing power, antibacterial, DNA binding, and DNA cleavage activities were tested. Then, all chiral dioxaborinane complexes were investigated as catalysts for the asymmetric transfer hydrogenation of various ketones under suitable conditions. The results indicated that the chiral dioxaborinane catalysts performed well with high yields.

Imidazo[1,2-a]pyridines form versatile scaffolds in pharmaceutical industry arising from their diverse biological activities. The synthesis of these molecules thus has been of great interest and resulted in the development of a large number of new methodologies. Herein we describe the first iron-catalyzed Ortoleva-King type protocol towards the synthesis of these fused heterocyclic compounds. This methodology employs cheap and easily available FeCl3 center dot 6H(2)O and molecular iodine as the catalytic system. The procedure has been well explored by extending the substrate scope with a variety of aromatic ketones and 2-aminopyridines to furnish different imidazo[1,2-a]pyridine derivatives in moderate to good yields. A successful application of this protocol was also demonstrated by achieving direct one step synthesis of the gastro protective drug, Zolimidine. (C) 2019 Elsevier Ltd. All rights reserved.

Formula: C14H11N. I found the field of Chemistry very interesting.

The CAS is 86-29-3. Through research, I have a further understanding and discovery of 2,2-Diphenylacetonitrile.

We have identified a novel one-pot method for the synthesis of beta-amino alcohols, which is based on C-H bond hydroxylation at the benzylic alpha-carbon atom with a subsequent nitrile or amide functional group reduction. This cascade process uses molecular oxygen as an oxidant and sodium bis(2-methoxyethoxy)aluminum hydride as a reductant. The substrate scope was examined on 30 entries and, although the respective products were provided in moderate yields only, the above simple protocol may serve as a direct and powerful entry to the sterically congested 1,2-amino alcohols that are difficult to prepare by other routes. The plausible mechanistic rationale for the observed results is given and the reaction was applied to a synthesis of a potentially bioactive target.

This study describes diversity-oriented synthesis of 2,2,3-substituted-2,3-dihydroquinolin-4(1H)-ones vs. functionalised quinoline or N-alkenylindole derivatives through Bronsted acid mediated or Lewis acid catalyzed sequential reactions of 2-alkynylanilines with ketones. In particular, a series of challenging quinolin-4-one derivatives are prepared with good functional group tolerance in an atom-economical fashion by using p-toluenesulfonic acid monohydrate as a promoter of the reaction of ketones with 2-alkynylanilines in EtOH at reflux, while the same starting materials give the corresponding 4-substituted quinolines in toluene at 110 degrees C both in the presence of p-toluenesulfonic acid monohydrate as the promoter and FeCl3 as the catalyst. The divergent formation of N-alkenylindole derivatives occurs by switching to the use of ZnBr2 as the catalyst under the same reaction conditions. Conversely, only 4-methylsubstituted quinoline derivatives were isolated by reacting 2-ethynylanilines and/or 2-trimethylsylilanilines with ketones in all examined cases.

Herein we report iodine-mediated multicomponent reactions for the synthesis of naphthoquinone-fused pyrroles tethered with a pyrimidine moiety. The reaction of aryl methyl ketones (3) or terminal aryl alkynes (5) in the presence of molecular iodine in DMSO medium followed by sequential addition of barbituric acids (2) and 2-amino-1,4-naphthoquinone (1) provides the corresponding three-component hybrid molecules 4 having naphthoquinone-fused pyrroles tethered with a barbituric acid moiety. This three-component reaction proceeds via metal-free C-H oxidation followed by multi-component cyclization forming three new bonds (2 C-C, 1 C-N) in one pot. Alternatively, the same molecules can also be prepared from the reaction of arylglyoxals, 2-aminonaphthoquinone, and barbituric acids in the presence of a catalytic amount of iodine in methanol medium under reflux conditions. The salient features of these methodologies are: one-pot metal-free method, good yields, wide substrate scope, easy purification of products, and the presence of medicinally important naphthoquinone, pyrrole and pyrimidine moieties in the products.

The Summary of main observation and conclusion An efficient palladium-catalyzed regioselective 5-exo aminotrifluoromethoxylation of alkenes has been established herein, which provides a practical route towards the synthesis of OCF3-containing pyrrolidines. tert-Butyloxycarbonyl (Boc) as an amino protecting group plays a significant role in both the chemo- and regioselectivities. In addition, preliminary mechanistic studies reveal that the amino protecting group of substrates and the counter anion of palladium catalyst play critical roles in reaction efficiency presumably due to an isomerization of alkyl- Pd(II) intermediates. Moreover, the asymmetric 5-exo aminotrifluoromethoxylation reaction has also been achieved by introducing a sterically bulky pyridinyl-oxazoline ligand.
