A green synthetic approach for dimethyl isosorbide (DMI) with dimethylcarbonate (DMC) in the presence of a base is reported. The easy methylation of isosorbide may be due to its unique structure (which enhances the nucleophilicity of the hydroxyl groups), and to the effect of the hydrogen bonding which increases the reactivity of the molecule towards DMC.
报道了在碱存在下用碳酸二甲酯(DMC)合成二甲基异山梨酯(DMI)的绿色合成方法。异山梨醇容易甲基化可能是由于其独特的结构(增强了羟基的亲核性),以及氢键的作用增加了分子对DMC的反应性。
