Readily available N-acylbenzotriazoles 2a-q efficiently acylate aqueous ammonia and primary and secondary amines to give primary, secondary, and tertiary amides in good to excellent yields. The wide applicability of the procedure is illustrated by the preparation of (i) alpha-hydroxyamides from alpha-hydroxy acids and of (ii) perfluoroalkylated amides.
易于获得的N-酰基苯并三唑2a-q有效地酰化氨水和伯胺和仲胺,从而以良好或优异的收率得到伯,仲和叔酰胺。该方法的广泛适用性通过(i)由α-羟基酸制备α-羟基酰胺和(ii)全氟烷基化酰胺来说明。
