Synthetic studies towards the preparation of 2-benzyl-2-hydroxybenzofuran-3-(2H)-one, the prototype of naturally occurring auronols

Abstract

Various synthetic approaches to preparation of 2-benzyl-2-hydroxybenzofuran-3-(2H)-one, the efficient method was implemented by hydrogenolytic epoxide-ring opening of 2'phenylspiro(benzofuran-2-(3H),2'-oxiran)-3-one
