An easy route to optically active 1-substituted-1-pyridyl-methylamines by diastereoselective reduction of enantiopure N-tert-butanesulfinyl ketimines
摘要:
The reduction of enantiopure N-tert-butanesulfinyl ketimines derived from pyridyl ketones afforded the related N-tert-but-anesulfinyl amines with high yields and diastereoselectivities. (c) 2006 Elsevier Ltd. All rights reserved.
