One-pot conversion of azides to Boc-protected amines with trimethylphosphine and Boc-ON
摘要:
Reaction of azides with trimethylphosphine followed by addition of 2-(tert-butoxycarbonyloxyimino)-2-phenyl- acetonitrile (Boc-ON) at -20 degrees C,and stirring at r.t. for 5 h affords the desired Boc-amines in 87-100% yields. Similar yields are obtained by mixing all components together (azide, Me3P, and Boc-ON) in toluene or THF. (C) 1998 Elsevier Science Ltd. All rights reserved.
