Intramolecular Heck-type Reactions in Aqueous Medium. A Dramatic Change in Regioselectivity

Efficient intramolecular Heck-type cyclizations were carried out in aqueous medium using water-soluble Pd/TPPTS catalysts. Under these conditions, the generally observed exo process was reversed in favor of the regioselective formation of endo cyclized compounds.
