The formation of methylene-bis derivatives of benzopyran-4-ones from their Mannich bases was studied. On these grounds, unsymmetrical methylene derivatives have been synthesized by reacting Mannich bases of benzopyran-4-ones with structurally related compounds lacking the dialkylaminomethyl group.
研究了由其曼尼希碱形成的苯并吡喃-4-酮的亚甲基双衍生物。基于这些理由,已经通过使苯并吡喃-4-酮的曼尼希碱与缺乏二烷基氨基甲基的结构相关化合物反应来合成不对称的亚甲基衍生物。
