An enantioselective synthesis of substituted 2-methyl chromans was accomplished in four steps using four sequential Pd-catalyzed reactions. A study of the key palladium-catalyzed regioselective aryl ether ring formation of two different substrates was also carried out to better understand the factors which affect the selectivity of the reaction.
使用四个连续的Pd催化反应,可在四个步骤中完成对位2-甲基苯并二氢吡喃的对映选择性合成。为了更好地了解影响反应选择性的因素,还对关键的钯催化的两种不同底物的区域选择性芳基醚环的形成进行了研究。
