Vinyl epoxides are excellent substrates for Pd-catalyzed allylic alkylations of chelated enolates. Nucleophilic attack on the predominantly formed syn/syn Ï-allyl complexes occurs regioselectively at the distal position. The E-configured product is formed preferentially, depending on the substitution pattern and the reaction conditions used.
乙烯基环氧化物是钯催化的配位酮醇化合物的烯丙基烷基化反应的优良底物。主要形成的顺/顺π-烯丙基复合物的亲核攻击通常发生在远端位点。E型构型的产物优先生成,这取决于取代基模式和所用的反应条件。
