Abstract
The title compound, C19H31NO5S, was prepared using a Wittig-Horner olefinat ion followed by an intramolecular Michael addition. Two diastereoisomers we re obtained in a 80:20 (beta:alpha) ratio. The stereochemistry of the major anomer (beta, thermodynamic) was based on NMR (C-13 and H-1) spectra. The present X-ray structure determination confirms the configuration of this pr oduct.
