Methyl coumalate readily reacts with enamines at ambient temperature to give lactones, which can be further transformed into isophthalates and tetrahydronaphthoates. Both cyclic and acyclic enamines show good reactivity. Dehydrogenation of tetrahydronaphthoate 4a was achieved on a hundred-gram scale.

从香豆酸甲酯到间苯二甲酸酯和萘酸酯的不同途径

香豆酸甲酯很容易在环境温度下与烯胺反应生成内酯,内酯可以进一步转化为间苯二甲酸酯和四氢萘甲酸酯。环状和无环烯胺都显示出良好的反应性。四氢萘甲酸酯4a的脱氢达到一百克规模。
