Benzocyclohexane derivatives were prepared highly stereoselectively by the cyclic Friedel-Crafts reaction of 6-acetoxy-4-alkenyl arenes in moderate to excellent yields in TFA HOAc (3:1). It was observed that the rate of the cyclization as well as the yields of products depend largely on the substituents of the allylic acetate moiety. (C) 2002 Elsevier Science Ltd. All rights reserved.
