Synthesis of N,N′,N”-Tri(3,5-Dinitro Benzenesulfonyl)-1,4,7-triazacyclononane and N,N′,N”-Tri(3,5-Diamino Benzenesulfonyl)-1,4,7-triazacyclononane

Abstract

An easy three step synthesis of N, N′, N”-tribenzenesulfonyl-1,4,7-triazacyclononane (I) was carried out in good yields and short reaction times starting from diethylenetriamine, 1,2-ethandiol and benzene sulfochloride. The first synthsis of nitro and amino derivatives of I was reported in detail.
