InCl3-catalyzed allylic Friedel-Crafts reactions toward the stereocontrolled synthesis of 1,2,3,4-tetrahydroquinolines.

Allyl chlorides tethered to an N-aryl moiety readily undergo InCl(3)-catalyzed Friedel-Crafts reactions to furnish highly enantiomerically enriched 1,2,3,4-tetrahydroquinolines with good yields and excellent diastereoselectivity.
