摘要:
The highly stereoselective total synthesis of polyacetate alpha,beta-unsaturated delta-lactone natural product (+)-synargentolide A has been accomplished from inexpensive D-1,5-gluconolactone. Key reactions involved in the synthesis are hydroboration, Wittig olefination, Brown's asymmetric allylation, and a ring closing metathesis reaction. (C) 2012 Elsevier Ltd. All rights reserved.
