Gold(I)-catalysed one-pot synthesis of chromans using allylic alcohols and phenols

Beilstein J Org Chem. 2013 Sep 4:9:1797-806. doi: 10.3762/bjoc.9.209. eCollection 2013.

Abstract

A gold(I)-catalysed reaction of allylic alcohols and phenols produces chromans regioselectively via a one-pot Friedel-Crafts allylation/intramolecular hydroalkoxylation sequence. The reaction is mild, practical and tolerant of a wide variety of substituents on the phenol.

Keywords: Friedel–Crafts; allylic alcohols; chromans; gold catalysis; heterocycles.
