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 use of these protecting/activating groups.

A series of N-aryl ortho-substituted glycines and alanines, which serve as useful intermediates for the synthesis of N1-aryl-substituted imidazolidine-2,4-diones and their 2-thioxo analogues, have been prepared and characterized by their infrar
