A New Entry to Functionalized 4-Aryl-2-methylenetetralones

Abstract

A new SnCl₄-induced rearrangement of 2,5-diaryl-2,3-dihydrofurans allows a direct and efficient formation of the 4-aryl-2-methylenetetralone skeleton. Its scope and limitations are discussed.

2,3-dihydrofurans - methylenetetralones - rearrangements - Lewis acids - ring-opening
