Abstract

Abstract: The results of a broad investigation of the preparative and mechanistic aspects of single electron transfer (SET) promoted photocyclization reactions of a-silyl amino and amido a,@-unsaturated esters and ketones are presented. A number of unique and synthetically useful features of these processes, driven by a-silyl amine and amide cation radical desilylation and by intramolecular conjugate addition of intermediate a-amino and ...
