Thermolytic Synthesis of Naphthalenes via Intramolecular Cyclocondensation of o-Phenylallylbenzaldehydes

Abstract

The development of intramolecular carbonyl-ene type cyclocondensation of oxygenated o-phenylallylbenzaldehydes in refluxing decalin is reported. The facile and easy-to-operate thermolytic rearrangement procedure generates substituted naphthalenes in good to excellent yields.

Key words

carbonyl-ene type - cyclocondensation - o-carbonyl allylbenzenes - substituted naphthalenes
