取代萘并吡喃的合成和晶体结构研究

Synthesis and Crystal Structure of Substituted Naphthopyran

以芳醛、丙二腈(或氰乙酸酯)、β-萘酚为原料在六氢吡啶存在下以乙醇为溶剂一锅合成了取代萘并吡喃,产物的结构通过单晶X射线衍射分析确定。

The substituted naphthopyrans have been synthesized by the reaction of aromatic aldehydes with malononitrile (or ethyl cyanoacetate) and beta-naphthol in ethanol at reflux in the presence of piperidine. The structure of 4h was determined by single-crystal X-ray diffraction study.
