  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.
