Multicomponent Cascade Reaction by Metal-Free Aerobic Oxidation for Synthesis of Highly Functionalized 2-Amino-4-coumarinyl-5-arylpyrroles
A novel approach has been constructed for the synthesis of two types of 2-amino-4-coumarinyl-5-arylpyrroles (ACAPs, 5 and 6) through a cascade reaction and a metal-free catalyzed aerobic oxidation reaction of arylglyoxal monohydrates 1, 1,1-enediamines (E
The synthesis of fluoroheterocyclic ketene aminals
The synthesis of fluoroheterocyclic ketene aminals was investigated. Fluorobenzyl ketene dithioacetals 1c reacted with nitric acid in the presence of concentrated sulfuric acid to give compound 2c. 1 reacted with diamines to afford 3-4. C-fluorobenzylatio
