Abstract
The thiatricycle (2S, 6R, 8S, 12S)-(2), prepared in one pot by reactio n of (5S)-5-phenylmorpholinone with (prop-2-enyl)thioethanal, is conve rted stereoselectively to sulfoxide (5) which undergoes regio- and ste reoselective Pummerer rearrangement. Subsequent elaboration furnishes (2S, 4R, 5S)-5-(hydroxymethyl)-4-methylproline (9).
