There are provided novel and optically active 2,2-dimethyl-1,3-dioxin-4-ones which are useful as starting materials for physiologically active compounds, functional materials or the like. Furthermore, a method for preparing an optically active compound comprises reacting a racemic 1,3-dioxin-4-one with vinylacetate in the presence of lipase to resolve the racemic compound into optically active compound represented by the formula (3) ##STR1## and an optically active compound represented by the formula (4) ##STR2## which is an antipode of the compound represented by the formula (3).
提供了一种新型的光学活性2,2-二甲基-1,3-二氧杂环丁酮,可用作生理活性化合物、功能材料等的起始材料。此外,一种制备光学活性化合物的方法包括在脂肪酶存在下,将外消旋1,3-二氧杂环丁酮与醋酸乙烯基反应,将外消旋化合物分解成代表公式(3)的光学活性化合物和代表公式(4)的光学活性化合物,后者是代表公式(3)化合物的对映异构体。
