摘要
The natural product ascomycin represents a highly functionalised 23-membered macrocycle with a polyketide backbone. Within the binding domain, ascomycin features the unusual pattern of a masked tricarbonyl moiety, which potentially allows for high structural diversity via simple isomerisation events. Herein, highly stereoselective, hydroxide mediated rearrangement reactions at the binding domain are reported. (C) 2004 Elsevier Ltd. All rights reserved.
