摘要：

A new one-pot method is described for the removal of O-allyl protecting groups under oxidative conditions at neutral pH. 2'-Allyloxychalcones undergo deprotection and subsequent oxidative cyclisation to give flavones. The general applicability of the reagent has been studied. (C) 2005 Published by Elsevier Ltd.
