Intramolecular Trapping of Esters by 1-Lithio-1-bromocyclopropanes
摘要:
Reaction of 2-acyloxymethyl-1,1-dibromocyclopropanes with methyllithium at -90 degrees C leads to selective bromine-lithium exchange and intramolecular cyclisation to give a 1-bromo-3-oxabicyclo[3.1.0]hexan-2-ol. (C) 2000 Elsevier Science Ltd. All rights reserved.
