Aliphatic nitroalkanes with different functional groups were synthesized from the Michael addition reactions of active methylene compounds 2 and nitrovinyl arenes 1 in high yields. The synthesized Michael adducts were subjected to intramolecular cyclization to give heteroaryl substituted γ-lactams in good to high yields under mild reaction conditions.
通过活泼的亚甲基化合物2与
硝基乙烯芳烃1的迈克尔加成反应,合成了具有不同功能团的脂肪族硝基
烷烃,产率较高。合成的迈克尔加成产物经受分子内环化反应,在温和反应条件下成功生成了杂芳基取代的γ-内酰胺,产率从良好到高。
