Processes of forming Csp2—Csp3 bonds at the allylic carbon of a cyclic allylic compound starting material are disclosed, in which a racemic mixture of a cyclic allylic compound having a leaving group attached to the allylic carbon is reacted with a compound having a nucleophilic carbon atom in the presence of a Rh(I), Pd(II) or Cu(I) pre-catalyst and a chiral ligand. The reaction products containing the newly-formed Csp2—Csp3 bond are generated in high stereoisomeric excess, and may therefore serve as important organic building blocks in the preparation of new agrochemicals and pharmaceuticals.
本发明公开了在环状烯丙基化合物起始原料的烯丙基碳上形成 Csp2-Csp3 键的工艺,其中在 Rh(I)、Pd(II) 或 Cu(I) 前催化剂和手性配体的存在下,烯丙基碳上连接有离去基团的环状烯丙基化合物的外消旋混合物与具有亲核碳原子的化合物发生反应。含有新形成的 Csp2-Csp3 键的反应产物具有很高的立体异构过量,因此可作为制备新型农用化学品和药物的重要有机构件。
