synthesized by the reaction of arylisothiocyanates with 4-hydroxy-6-methylpyran-2-one and 4-hydroxycoumarin, respectively. Novel products 3-[bis(arylamino)methylene]-6-methyl-2H,4H-pyran-2,4-diones and N,N′-diaryl-4-hydroxycoumarin-3-carboximidamides have also been obtained in the same reactions. Novel 4-acetoacetyl-3-phenylamino-4,5-dihydro-5H-pyrazol-5-ones were synthesized from the reaction of N-aryl-4
N-芳基-4-羟基-6-甲基-2 H-吡喃-2-一-3-碳硫酰胺和N-芳基-4-羟基香豆素-3-碳硫酰胺是通过芳基异硫氰酸酯与4-羟基-6-甲基吡喃-2-酮和4-羟基香豆素。新型产品3- [双(芳基氨基)亚甲基] -6-甲基-2 H,4 H-吡喃-2,4-二酮和N,N'-二芳基-4-羟基香豆素-3-羧酰亚胺衍生物也已获得。同样的反应。由N-芳基-4-羟基-6-甲基-2 H-吡喃-2-one-反应合成了新型的4-乙酰乙酰基-3-苯基氨基-4,5-二氢-5 H-吡唑-5-酮。 3-碳硫酰胺与过量的肼。通过NMR和质谱确定所有化合物的结构。J.杂环化学,(2009)。
