Abstract
A 4-phenylthiophene tethered to the 5-position of the heterocycle was synthesized from 1-benzosuberone. The key steps in the synthesis were the tandem thiolacetate hydrolysis - Michael addition intramolecular W ittig reaction ((5) under bar --> (7) under bar) and the chelation-con trolled reduction of the hydroxy beta-ketoester (<(12)under bar> --> < (13)under bar>). The product <(14)under bar> exhibited nearly identica l in vivo potency to the non-tethered analogs.
