Palladium catalyzed cross coupling reactions of (arylvinyl)tributyl stannanes with vinyl triflates resulted in the production of stereochemically pure trisubstituted E- and Z-olefins in very good yields. These olefins were transformed to the corresponding all-E- and 9Z-heteroaryl-retinoic acid analogs via Horner-Emmons reaction and subsequent basic hydrolysis in excellent yields.
钯催化的(芳基乙烯基)三丁基锡与乙烯基三氟甲磺酸酯的交叉耦合反应,以优异的产率生成了立体化学纯的E-和Z-三取代烯烃。这些烯烃通过Horner-Emmons反应和随后的碱性水解,以出色的产率转化为相应的全E-和9Z-杂芳基维甲酸类似物。
