PROBLEM TO BE SOLVED: To provide a synthesis method of 1,3-dioxolane or 2-hydroxycarboxylic acid ester having improved, moderate and technically performable temperature-sensitive and/or acid-sensitive functional groups.SOLUTION: 1,3-dioxolane-2-one represented by the general formula (3) is prepared by a basic catalyst and further 2-hydroxycarboxylic acid ester represented by the general formula (5) is prepared by the basic catalyst. In general formula (3) and general formula (5), Rand Rare a hydrogen atom, an aryl or a heteroaryl group and the like, Rand Rare a saturated or a monovalent or a polyvalent unsaturated carbon ring and the like, and Ris an organic group. |
