Allylic gem-dichlorides undergo regio- and enanantioselective (er up to 99:1) copper-catalyzed allylic alkylation with Grignard reagents affording chiral Z-vinyl chlorides. This highly versatile class of synthons can be subjected to Suzuki cross coupling affording optically active Z-alkenes and 1,3-cis,trans dienes.
烯丙基二氯化物经过区域选择性和对映选择性(高达 99:1)铜催化的烯丙基烷基化与格氏试剂,得到手性 Z-氯乙烯。这种高度通用的合成子类可以进行 Suzuki 交叉耦合,提供光学活性 Z-烯烃和 1,3-顺式,反式二烯。
