ABSTRACT:
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).
