摘要
在乙腈溶液中,6,6'-二甲基-4,4'-(三亚甲二氧基)-二-2-吡喃酮与乙二醇二甲基丙烯酸酯类化合物(n=1~3)在二苯酮的光敏化作用下,经由光二重[2+2]环加成反应,同时合成了2种氧杂类的大环化合物,收率为14%和7%、20%和11%及31%和14%。产物的结构经FTIR、1H NMR和MS表征。该法具有反应条件温和、操作简单和对环境友好的优点。
Two oxa macrocyclic compounds were synthesized via double photocycloaddition reaction between 6,6′-dimethyl-4,4′-(trimethylenedioxy)-di-2-pyrone and ethylene glycol dimethacrylates(n=1-3) by photosensitizing effect of benzophenone in acetonitrile solution with yields of 14% and 7%,20% and 11%,31% and 14%,respectively.The structures of products were identified by FTIR,1H NMR,MS and elemental analysis.The synthetic method has several advantages such as mild reaction conditions,simple operation and environmental friendliness.
