摘要

2, 4-Dinitrobenzenesulfonamides, readily prepared from primary amines and 2, 4- dinitrobenzenesulfonyl chloride, can be alkylated by the Mitsunobu reaction or by the conventional methods to give N, N-disubstituted sulfonamides in excellent yields. Since 2, 4- dinitrobenzenesulfonamides can be removed without deprotecting 2- nitrobenzenesulfonamides, a wide variety of diamines could be prepared by the combined ...
