Abstract

A general and efficient procedure for the stereoselective synthesis of (E)-(1-propenyl) phenyl esters from readily accessible allylphenols has been developed. The process involves a two- step sequence consisting of the initial acylation of the allylphenols with an acid chloride, followed by catalytic CC bond isomerization in the resulting allylphenyl esters. The latter step was performed in methanol at 80° C using catalytic amounts (0.5 mol%) of the ...
