Switching the regioselectivity of acid-catalyzed reactions of arylnaphtho[2,1-b]furans via a [1,2]-aryl shift

Abstract

The straightforward approach involving a [1,2]-aryl shift provides access to a wide range of aryl-substituted naphtho[2,1-b]furans. Switching of the regioselectivity of acid-catalyzed reactions of arylnaphtho[2,1-b]furans has been demonstrated.
