BF3·OEt2 mediated regioselective deacetylation of polyacetoxyacetophenones and its application in the synthesis of natural products
摘要:
We have developed an efficient method to regioselectively deacetylate polyacetoxyacetophenones using BF(3)center dot OEt(2) in excellent yields and demonstrated the application of the procedure in the synthesis of natural products. (C) 2008 Elsevier Ltd All rights reserved.
