Abstract

In the transition metal catalyzed C–H insertion of α-diazoacetamide, regioselectivity has remained a major challenge. It has been well documented that regioselectivity depends highly on the substitutents of diazo carbon, the N-substitutents on the amide moiety, and the electrophilicity of the catalysts. 5 In the past twenty years, some examples have been reported on the application of the intramolecular C–H insertion of α-diazoacetamide. 6 High regioselectivity has been ...
