Visible-Light-Induced Regioselective C(sp3)-H Acyloxylation of Aryl-2H-azirines with (Diacetoxy)iodobenzene
摘要:
A visible-light-promoted regioselective coupling of C(sp(3))-H of aryl-2H-azirine and (diacetoxy)-iodobenzene has been reported. Rose Bengal as an organo-photoredox catalyst has been used in this reaction. The reaction proceeds under aerobic condition at room temperature. A variety of aryl-2H-azirines gives the corresponding acyloxylated azirines under this reaction conditions. The reaction goes through a radical pathway. The protocol is also applicable on gram-scale synthesis.

by the reaction of 3-aryl-2H-azirines and highly substituted 2-Me/Ph-3-aryl-2H-azirines with various carboxylic acids under ambient air within 10 min at room temperature. N-Trifluoroacetylated α-aminoketones with different substituents have been reported in the presence of trifluoroacetic acid. This protocol is equally effective to synthesize N-formylated α-aminoketone and N-hydroxymethylated formamide
