  Regioselective modification of amino groups in aminoglycosides based on cyclic carbamate formation

  摘要：

  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 neat-nine, 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. (C) 2008 Elsevier Ltd. All rights reserved.

  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 carbamate is an intermediate of the deprotection reaction. The selective deprotection of the amine protecting group enable us to synthesize several kanamycin A dimers linked at N-3 '' position in a straightforward way. (C) 2009 Elsevier Ltd.
