Intramolecular trapping of amides by 1-lithio-1-bromocyclopropanes
摘要:
Reaction of 2-acylaminomethyl-1,1-dibromocyclopropanes with methyllithium at -90 degreesC leads to selective bromine-lithium exchange and cyclisation to give a 1-bromo-3-azabicyclo[3.1.0]hexan-2-ol. (C) 2001 Elsevier Science Ltd. All rights reserved.
