THE APPLICATION OF HIGHLY STEREOSELECTIVE ALDOL CONDENSATIONS TO THE SYNTHESIS OF β-LACTAM ANTIBIOTICS.

Stereoselective aldol condensations of fully protected glycine and 3-butyryl thiazolidine-2-thiones with achiral aldehydes afforded β-hydroxyesters suitable for elaboration to key intermediates for the synthesis of β-lactam antibiotics.
