Sahoo, Subas Chandra published the artcileDirect Aerobic Oxidative Reactions of 2-Hydroxyacetophenones, Quality Control of 40353-41-1, the main research area is phthalide preparation; isochromandione hydroxyacetophenone aerobic oxidation; quinoxaline preparation; diamine aryl hydroxyacetophenone aerobic oxidation; amide keto preparation; pyrrolidine hydroxyacetophenone aerobic oxidation.
Valuable and direct aerobic oxidation reactions of 2-hydroxyacetophenones R1C(O)CH2OH (R1 = thien-2-yl, 2H-1,3-benzodioxol-5-yl, 2-O2NC6H4, etc.) were explored. The concept was based on the in situ treatment of small quantities of aerobically formed α-keto aldehydes that drove the reactions to the corresponding products. This new strategy was applied for a variety of oxidative reactions of 2-hydroxyacetophenones, and valuable products such as phthalides I (R2 = H, 7-CH3O), quinoxalines II (R3 = H, 6,7-Cl2, 6-NO2) and α-keto amides R1(C(O))2X (X = pyrrolidin-1-yl) were obtained in good to high yields.
European Journal of Organic Chemistry published new progress about Amides, oxo Role: SPN (Synthetic Preparation), PREP (Preparation). 40353-41-1 belongs to class quinoxaline, name is 2-(Thiophen-2-yl)quinoxaline, and the molecular formula is C12H8N2S, Quality Control of 40353-41-1.
