摘要

The use of an aryl allyl ether and an arylallyl group as masked vinyl ether and 1- propenylphenyl groups for ring-closing metathesis (RCM) leading to the synthesis of benzo- fused heterocycles was demonstrated by using a ruthenium-mediated isomerization followed by a ruthenium-mediated RCM reaction. This resulted in the syntheses of a variety of products including two substituted benzo [1, 4] dioxins, a naphtho [2, 3-b][1, 4] dioxin, a ...
