Silver(I) promotes the highly chemoselective N-amidation of tertiary amines under catalytic conditions to form aminimides by nitrene transfer from PhI═NTs. Remarkably, this transformation proceeds in a selective manner in the presence of olefins and other functional groups without formation of the commonly observed aziridines or C-H insertion products. The methodology can be applied not only to rather

The present invention provides an industrial production method with a short process having a high yield of an aliphatic cyclic carboxamide having carboxyl group, which comprises reacting functional group-selectively using an inexpensive condensing agent without protecting the carboxyl group by esterification, that is, reacting carboxylic acid anhydride obtained by reacting carboxylic acid and tertiary carboxylic acid halide with aliphatic cyclic secondary amine having carboxyl group.
