Novel synthesis of Nectrisine and 4-epi-Nectrisine
摘要:
Nectrisine 1, a potent glycosidase inhibitor, and 4-epi-Nectrisine 2 were synthesized from D-(-)-diethyl tartrate through the corresponding lactams. N-acyl protection was crucial to effect the reduction of the corresponding lactam to amino alcohols (C) 1997 Elsevier Science Ltd.
enantioselective synthesis of (−)-syringolides 1 and 2 which were isolated as specific elicitors produced by Pseudomonas syringae pv. tomato was accomplished in 11 steps from diethyl d tartrate. The specific rotations of synthetic samples were in good accord with those of the natural syringolides, and synthetic syringolide2 showed almost the same biological activity as that of natural syringolide2.
