MAD as an additive : The [Ni(cod) 2 ], (2,6‐ t Bu 2 ‐4‐MeC 6 H 2 O) 2 AlMe (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.
