摘要:
The total synthesis of three natural products isolated from Nigrospora sp., Phoma sp., and Aspergillus nidulans(l) starting from an aldol reaction with a homochiral C-4-oxa-vinylogous urethane is described. Inherent stereoselectivity of the aldol reaction and overall alacrity of molecular construction are discussed. (C) 1999 Elsevier Science Ltd. All rights reserved.
