A simple and environmentally friendly strategy for the synthesis of E-ortho-hydroxystilbenes has been established. Two kinds of α,β-unsaturated aromatic lactones, i.e. the 3-arylcoumarins and the isoaurones, could both readily undergo a cascade hydrolyzation/decarboxylation reaction in the presence of KOH in ethylene glycol to afford the desired E-ortho-hydroxystilbenes in moderate to high yields.

α，β-不饱和芳族内酯的脱羧作用：由3-芳基香豆素或异金龙酮合成E-邻-羟基对苯二酚

已经建立了一种简单且对环境友好的策略，用于合成E-邻-羟基对苯二酚。两种α，β不饱和芳族内酯，的即3-arylcoumarins和isoaurones，既可以容易地进行在KOH的存在下水解级联/脱羧反应在乙二醇，得到期望的E-邻-hydroxystilbenes在中度至高产。
