Abstract
The title compound, C22H39NO6S, is obtained by an intramolecular cyclization of the adduct resulting from the Michael addition of a chiral homoenolate to a cyclic alpha-enone. Its absolute stereochemistry is unambiguously established and this will provide an insight into the mechanism of the addition step of the reaction.
