MAD as an additive: The [Ni(cod)2], (2,6‐tBu2‐4‐MeC6H2O)2AlMe (MAD), and N‐heterocyclic carbene (NHC) catalytic system effected a highly regioselective alkylation of pyridone derivatives (see scheme). Substituted pyridones and related heterocycles react with both terminal and internal alkenes to selectively give a range of nitrogen‐containing heterocycles with linear alkyl substituents.
MAD作为添加剂:[Ni(cod)2 ],(2,6 - t Bu 2-4 -MeC 6 H 2 O)2 AlMe(MAD)和N-杂环卡宾(NHC)催化体系产生了很高的吡啶酮衍生物的区域选择性烷基化(参见方案)。取代的吡啶酮和相关的杂环与末端和内部烯烃反应,从而选择性地生成一系列具有线性烷基取代基的含氮杂环。
