, p. 925 - 929 (2012/06/15)
A synthetic route for the preparation of 2-aryl-substituted chromans from commercially available starting materials and utilizing either a palladium- or copper-catalyzed intramolecular cyclization of aryl bromides is described. Chromans with stereocontrol at C-2 can thus be obtained via a palladium-catalyzed asymmetric allylic etherification procedure utilizing a chiral indole-phosphine oxazoline (IndPHOX) ligand.
