Synthetic methods : An asymmetric catalytic, desulfonylative Mannich reaction of α‐keto imines with aldehydes, as catalyzed by diarylprolinol silyl ether 1 , was developed. It gave the Mannich product in good yield with excellent anti and enantioselectivity (see scheme; Boc= tert ‐butoxycarbonyl, TMS=trimethylsilyl).
