Barbituric or 2-thiobarbituric acids interact with o-dialkylaminobenzaldehydes to give 5-o-dialkylaminobenzylidene derivatives, which cyclise into 2,4,6-trioxoperhydropyrimidine-5-spiro-3′-(1′,2′,3′,4′-tetrahydroquinolines) under mild conditions; the mechanism of the key stage of a tert-amino effect reaction is disclosed on the basis of the XRD analysis of 1,3-dimethyl-5-(2-dimethylamino-4-nitrobe
巴比妥酸或2-硫代巴比妥酸与邻二烷基氨基苯甲醛相互作用生成5-邻二烷基氨基苄叉基衍生物,该衍生物环化成2,4,6-三氧杂氢嘧啶-5-螺-3'-(1',2',3',4' -四氢喹啉)在温和的条件下; 基于1,3-二甲基-5-(2-二甲基氨基-4-硝基亚苄基)巴比妥酸的XRD分析,揭示了叔氨基效应反应关键阶段的机理。
