of conjugate addition reactions have been performed with vinyl-substituted N-heterocycles in acid-catalyzed conversions. Using active methylene compounds, double conjugate addition reactions have been accomplished to provide dipyridyl and related heterocyclic products. These conversions have utilized 1,3-dicarbonyl compounds, cyano esters, a cyano sulfone, and malonyl nitrile as nucleophiles. The Michael
在酸催化转化中,已经用乙烯基取代的 N-杂环进行了一系列共轭加成反应。使用活性亚甲基化合物,已完成双共轭加成反应以提供联吡啶和相关杂环产物。这些转化使用 1,3-二羰基化合物、氰基酯、氰基砜和丙二腈作为亲核试剂。迈克尔接受基团包括乙烯基取代的吡啶、喹啉和吡嗪。用 2,6-二乙烯基吡啶和相关系统也完成了双共轭加成反应。
