The TMSOTf mediated nucleophilic cleavage of alpha -aminoacetals can be used to prepare a variety of substituted amines, with variable levels of stereocontrol depending on the substitution patterns. The reaction most likely proceeds via either an alpha -alkoxy aziridinium ion or an alpha -oxocarbenium ion depending on the type of nucleophile. (C) 2001 Elsevier Science Ltd. All rights reserved.
