Substituted 2-amino-4-aryl-3-cyano-5-oxo-5,6-dihydro-4H-pyrano[2,3-d]pyrido[3",2":4,5]thieno[3,2-b]pyridines were synthesized by the reactions of 4-hydroxy-1H-thieno[2,3-b;4,5-b]dipyridin-2-ones with arylidenemalononitriles or by the three-component reactions of hydroxythienodipyridinones with aldehydes and malononitrile in DMF in the presence of triethylamine. Methods for syntheses of substituted
取代的 2-amino-4-aryl-3-cyano-5-oxo-5,6-dihydro-4H-pyrano[2,3-d]pyrido[3",2":4,5]thieno[3,2 -b]吡啶是通过 4-羟基-1H-噻吩并[2,3-b;4,5-b]二吡啶-2-酮与亚芳基丙二腈的反应或羟基噻吩二吡啶酮与醛和丙二腈的三组分反应合成的在三乙胺存在下的 DMF 中。在4-(3-cyanopyridin-2-)反应的基础上,开发了取代3-烷氧基羰基-6-氨基-4-芳基-2-(3-氰基吡啶-2-基硫甲基)-4H-吡喃的合成方法。硫代)乙酰乙酸酯和亚芳基丙二腈或醛和丙二腈。4-(3-氰基吡啶-2-基硫基)乙酰乙酸乙酯和4-甲氧基亚苄基氰基硫代乙酰胺用于合成6-(吡啶-2-基硫甲基)-3-氰基吡啶-2(1H)-硫酮。
