A brief and facile synthesis of the title compounds has been developed by using an efficient lipase-catalyzed acylation and a chiral template-directed diastereoselective alkylation for incorporating the stereogenic centres. A cross-metathesis was employed to get the required E-olefin geometry. (C) 2009 Elsevier Ltd. All rights reserved.
Stereoselective total synthesis of (+)-mueggelone, a novel inhibitor of fish development
An efficient stereoselective totalsynthesis of (+)-mueggelone, a novelinhibitor of fish development, is described. Highlights of the strategy include the utilization of Sharpless asymmetric epoxidation, Yamaguchi lactonization and an olefin cross-metathesis as the key steps.
