Recently I am researching about ONE-POT SYNTHESIS; OXIDATIVE SYNTHESIS; 2-SUBSTITUTED BENZIMIDAZOLES; SUBSTITUTED BENZOTHIAZOLES; ARYL KETONES; EFFICIENT; CYCLIZATION; ACCESS; MILD; ACID, Saw an article supported by the Leading Innovative and Entrepreneur Team Introduction Program of Zhejiang [2019R01005]. Category: benzodioxans. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Ma, RC; Ding, YX; Chen, R; Wang, ZM; Wang, L; Ma, YM. The CAS is 100-19-6. Through research, I have a further understanding and discovery of 1-(4-Nitrophenyl)ethanone
A simple and practical domino protocol for the selective synthesis of 2-aroylbenzothiazoles and 2-aryl benzothiazoles catalyzed by I-2 is developed under metal-free conditions. The reaction outcomes are exclusively controlled by the reaction oxidant/medium. With DMSO employed as both the solvent and the oxidant, an oxidation of aromatic methyl ketones takes precedence over the condensation with 2-aminobenzenethiols. On the other hand, when the reaction was carried out in PhNO2 or in 1,4-dioxane containing PhNO2, the condensation of aromatic methyl ketones with 2-aminobenzenethiols has priority to form imines which is followed by an oxidation of the methyl group from ketones to afford 2-arylbenzothiazoles as a sole product. The PhNO2/I-2 co-catalytic system is proposed first time.
