  N-hydroxy-5-norbornene-2,3-dicarboximide ester of N-benzyloxycarbonyl-DL-2-hydroxy-3-aminopropanoic acid 、 1,2',6'-tri-N-(benzyloxycarbonyl)fortimicin B 以 四氢呋喃 、 1,4-二氧六环 为溶剂， 反应 48.0h， 以1.08 g的产率得到1,2',6',3''-N-benzyloxycarbonyl-4-N-(D,L-3-amino-2-hydroxypropanoyl)fortimicin B

  名称：

  4-N-acylfortimicins b and the preparation of fortimicin a from fortimicin B

  摘要：

  Selective 4-N-acylation of fortimicin B (2) has been accomplished by 4-N-acylation of 1,2',6'-tri-N-benzyloxycarbonylfortimicin B (4) followed by hydrogenolysis of the N-protecting benzyloxycarbonyl groups. In this manner, fortimicin B was converted into fortimicin A (1), and a series of 4-N-acylfortimicins B (3) was prepared for antibacterial assay. The key intermediate, 1,2',6'-tri-N-benzyloxycarbonylfortimicin B, was prepared either directly from fortimicin B or by converting fortimicin A into 1,2',6',2''-tetra-N-benzyloxycarbonylfortimicin A (6a), followed by selective hydrolysis of the 4-N-(N-benzyloxycarbonyl)glycyl group of the latter.
