A simple, rapid, one-step synthesis of aryl' poly ethers from aryl acetates: improved synthesis of hexaalkoxytricycloquinazoline derivatives

Abstract

Aryl acetates when heated with alkyl halide in DMSO in the presence of powdered KOH undergo alkylation giving aryl ethers in high yields. Several hexasubstituted tricyc1oquinazoline and hexasubstituted triphenylene discotic liquid crystals were prepared conveniently from their acetates. Though better direct synthetic methods are available for the synthesis of alkoxy triphenylenes, this method is more efficacious in the case of tricyc1oquinazoline derivatives and results in several-fold increase in yield.
