Enantiospecific synthesis of (−)-muricatacin, a bio-active lactone comprising of a 5-hydroxyalkylbutan-4-olide structural component has been achieved froml-(+)-tartaricacid. The key step involves a disteroselective reduction of a C2-symmetric 1,4-diketone derived from tartaric acid followed by a selective Grignard reagent addition.
Total synthesis of (−)-muricatacin, a natural acetogenin, has been achieved using as a key step a regio- and stereospecific ring-opening of a substituted vinyl epoxide under Lewis acid catalysis.
