Asymmetric synthesis of α,α-diaryl and α-aryl-α-heteroaryl alkylamines by organometallic additions to N-tert- butanesulfinyl ketimines
摘要:
Organometallic addition to tert-butanesufinyl ketimines derived from diaryl and aryl-heteroaryl ketones provided the corresponding alpha,alpha -diaryl and alpha -aryl-alpha -heteroaryl alkylamines in good yield with high diastereoselectivity. In many cases, imine facial selectivity is reversed on changing the organometallic counterion. (C) 2001 Published by Elsevier Science Ltd.
