An efficient method for the synthesis of N,N′-dimethyl-1,2-diamines
摘要:
A simple method for the preparation of N,N'-dimethyl-1,2-diamines is described. The method requires the dimethylation of a diazaphospholidine oxide followed by acid-catalysed hydrolysis. (C) 2001 Elsevier Science Ltd. All rights reserved.

We have identified a new class of catalysts for the asymmetricreduction of prochiral ketones by borane. Key to the architecture of effective catalysts is an N–PO structural unit which may be part of a phosphinamide, phosphonamide or a related structure. Such catalysts are simple to prepare, are often crystalline solids and may be recovered from reduction reactions and reused. The catalysts act essentially
