摘 要: 以马尿酸、原甲酸三乙酯和乙酰乙酸乙酯或乙酰丙酮为原料,合成了两个3-苯甲酰胺基-6-甲基-2-吡喃酮衍生物(总产率66%)和一个新化合物——3-苯甲酰胺基-5-羟乙基-6-甲基-2-吡喃酮(总产率42%),其结构经1H NMR和13C NMR表征。 Two 3-benzoylamino-6-methylpyran-2-one derivatives and a new compound,3-benzoylamino-5-(1-hydroxyehtyl)-6-methyl-pyran-2-one,were synthesized from hippuric acid,ethyl orthoformate,ethyl acetoacetate or acetyl acetone.The total yield were 66% and 42%,respectively.The structures were characterized by 1H NMR and 13C NMR.
