Enantioselective synthesis of neoambrosin, parthenin, and dihydroisoparthenin
摘要:
Enantioselective synthesis of the titled ambrosanolides is described. Use of the trimethylsilyl group as an anchor contributed to the stereoselective introduction of two methyl groups.

Enantioselective synthesis of clavukerin A and itsepimer was carried out. By the comparison of the spectral data and specific rotations of synthesized and natural ones, two trisnorsesquiterpens isolated from Clavulia and Cespitularia species are confirmed to be identical.
