在浓硫酸催化下, 2-氨基-3-氰基-4H-吡喃类化合物与乙酸酐反应, 较高产率地合成了一系列吡喃并[2,3-d]嘧啶酮衍生物. 该方法反应时间短(10~15 min)、操作简单、后处理方便. 所合成产物的结构经红外光谱、核磁共振谱表征确证, 其中化合物4a6a的结构还通过X 射线单晶衍射分析确认.

A series of pyrano[2,3-d]pyrimidine derivatives were synthesized by the reaction of 2-amino-3-cyano-4H-pyrans with acetic anhydride. This method has the advantages of short reaction times (10~15 min), simple operation and convenient post-treatment. All products were fully characterized by IR and 1H NMR spectra. The molecular structures of 4a and 6a were confirmed using single-crystal X-ray analyses.

Key words: pyrano[2,3-d]pyrimidine derivatives, 2-amino-3-cyano-4H-pyran derivatives, acid catalysis
