Alkylation of the dianion of 3-methyl-3-buten-2-ol, followed by acetylation and palladium-catalyzed 1,2-elimination reaction of the so obtained methylvinylcarbinol acetates allows to synthesize regioselectively 2-substituted 1,3-butadienyl compounds having high isomeric purity.
3-甲基-3-丁烯-2-醇的二价阴离子的烷基化,然后通过乙酰化和钯催化的1,2-消除的甲基乙烯基甲醇甲醛乙酸酯反应,可以合成区域选择性的2-取代的1,3-丁二烯基化合物高异构体纯度。
