✦ Synopsis

Abstract

In Wittig reaction of some α‐methyl‐ and α‐methylene‐substituted phosphorus ylides with o‐quinones, benzo[b]furan derivatives were obtained via the cyclization of the o‐vinylphenols, initially formed from the tautomerization of the corresponding intermediate o‐quinone methides.
