Synthesis and Crystal Structure of 9-Aryl-3,6-dimethyl-1,8-dioxo-2,7,10-trioxanthene

以芳醛、6 甲基 4 羟基 2 吡喃酮为原料 ,醋酸酐为溶剂合成了一系列 3 ,6 二甲基 9 芳基 1,8 二氧代 2 ,7,10 三氧杂蒽 ,产物的结构经红外、核磁、元素分析及X射线衍射法表征 ;

A series of 9-aryl-3,6-dimethyl-1,8-dioxo-2,7,10-trioxanthenes were synthesized by the reaction of aromatic aldehydes with 4-hydroxyl-6-methyl-2-pyranone in acetic anhydride. The structure of the product was determined by IR, 1H NMR, elemental analysis and X-ray diffraction analysis. A possible mechanism for this reaction is postulated.
