3-iodobenzo[b]furans and stannanyl ester afforded the stereoselective production of 9Z-retinoic acid esteranalogs in good yields. These esters were then converted to the corresponding acids via basic hydrolysis in excellent yields, and their biological activities were evaluated. The analog changed the connected position of polyene side chain from 2-position to 3-position of benzo[b]furan decreased the
