Three in one go: Unactivated dienes containing a cycloalkenyl moiety reacted with a range of substituted aryl halides in the presence of Pd(OAc)2/PPh3 to afford fused polycyclic heterocycles (see scheme). Three carbon–carbon bonds are formed in this domino reaction, which involves highly regioselective CC coupling and CH functionalization steps. DMF=N,N‐dimethylformamide; Bn=benzyl, Ts=p‐toluenesulfonyl
三合一:在Pd(OAc)2 / PPh 3存在下,含有环烯基部分的未活化二烯与一系列取代的芳基卤反应,生成稠合的多环杂环(参见方案)。在该多米诺反应中形成了三个碳-碳键,这涉及高度区域选择性的CC偶联和CH官能化步骤。
DMF = N,N-二甲基甲酰胺;Bn =苄基,Ts =对
甲苯磺酰基。
