摘要

A comprehensive series of mono-, di-and tri-bromo-3H-naphtho [2, 1-b] pyrans was synthesised by the traditional union of a 2-naphthol with an alkynol. The bromine atom (s) in these naphthopyrans was readily replaced by a vinyl group using a Suzuki coupling reaction with vinyl boronic anhydride pyridine complex. The efficiency of the Suzuki vinylation reaction decreases with the increasing number of bromine atoms to be substituted. The ...
