Jz. Gao et al., 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, Synthetic communications, 27(18), 1997, pp. 3219-3225
An easy three step synthesis of N,N',N ''-tribenzenesulfonyl-1,4,7-tri
azacyclonon (I) was carried out in good yields and short reaction time
s starting from diethylenetriamine, 1,2-ethandiol and benzene sulfochl
oride. The first synthsis of nitro and amino derivatives of I was repo
rted in detail.
