Synthetic strategy toward furyl- and benzofuryl-containing building blocks for organic materials

Abstract

A synthetic approach to furyl- and benzofuryl-containing building blocks utilizing easily accessible substrates is reported. Cascade acidcatalyzed reactions of 2-methylfuran with α,β-unsaturated carbonyl compounds or salicyl alcohols followed by oxidation afford function-alized furans and benzofurans, respectively. Synthetic potential of the obtained products was demonstrated by synthesizing hetarylsubstituted heterocycles, which may find an application in materials chemistry.
