The optimal conditions for the regioselective deprotection of per-N-Cbz-kanamycin A and the reaction mechanism was investigated. We found that the Cbz group at N-3″ position was selectively deprotected under milder basic conditions and the cyclic carbamat

Conditions for regioselective introduction of cyclic carbamate into per-N-Cbz neamine and per-N-Cbz kanamycin A have been found. The position and number of cyclic carbamate formed in these two aminoglycosides was controllable. On the base of selective cyclic carbamate formation, regioselective modification on N-1, N-6′ or both amino groups in neamine, and on N-6′, N-3″ or both amino groups in kanamycin A was achieved by ring-opening reaction with amines. A new neamine dimer linked at the N-1 was also synthesized with this method.
