The highly diastereoselective Mukaiyama-Michaelreaction has been realized by use of O,S-ketene silylacetals. Of special importance in this reaction is the effective tuning of the stereochemical course simply by changing the double bond geometry of ketenesilylacetals. Thus, both syn- and anti-Michael adducts can be obtained on the synthetically useful levels of stereochemical purity.
