Synthesis of Isoflavonoids Containing dioxy heterocyclic groups

本文报道含有3’,4’-亚甲二氧基,3’,4’-亚乙二氧基,3’,4’-三亚甲二氧基的异黄酮类化合物的合成,所得25个新化合物的结构经元素分析、~1H NMR谱确证;紫外光谱表明有异黄酮特征吸收。文中并对反应机理进行了探讨。

This paper reports the synthesis of isoflavonoids which contain 3 ', 4 ' -methylenedioxy, 3', 4' - ethylenedioxy, and 3', 4' - trimethylenedioxy groups. The structures of new compounds were confirmed by elemental analysis, UV and 1H NMR spectroscopies. The mechanism of the reactions was suggested .
