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(l), Pd(ll) or Cu(l) 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.
揭示了在环状烯丙基化合物起始物的烯丙基碳上形成Csp2-Csp3键的过程,其中将具有离去基团连接到烯丙基碳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在Rh(I)、Pd(II)或Cu(I)前催化剂和手性配体的存在下反应。生成含有新形成的Csp2-Csp3键的反应产物在高立体异构过量中产生,因此可以作为制备新的农药和药物中的重要有机构建块。
