we have developed the first aminocatalyzed anti-selective Mannich reaction of aldehydes with N-Cbz- and N-Boc-protected imines generated in situ from stable aamido sulfones 2. Besides the high level of efficiency and stereocontrol achieved, this approach introduces important synthetic advantages, by avoiding the requirement to preform the N-carbamoyl imines.

Abstract
we have developed the first aminocatalyzed anti-selective Mannich reaction of aldehydes with N-Cbz- and N-Boc-protected imines generated in situ from stable aamido sulfones 2. Besides the high level of efficiency and stereocontrol achieved, this approach introduces important synthetic advantages, by avoiding the requirement to preform the N-carbamoyl imines.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
