Abstract Diastereoselective and enantioselective reduction of the β-ketoester 3 by yeast to 4 provided the chiral starting material for a synthesis of 4RS,6S,7S-serricornine, having the same configuration as the natural product. This material was converted into optically active and diastereomerically pure 6S,7S-anhydro-serricornine ( 2 ).

Abstract By comparison of the CD-spectra of synthetic material with that of stegobinone it is established that stegobinone has the 2S, 3R-configuration. The stereochemistry at C-7 remains unknown at present.
