| titleOfInvention | METHOD FOR PRODUCING 1,3-DIOXOLAN-4-METHANOL COMPOUNDS |
| abstract | A process for preparing 1,3-dioxolane-4-methanol compounds in a racemic modification form or an optically active form having a high purity in a high yield in a simple and cost-effective manner. The process comprises allowing an alkali (earth) metal salt of an alcohol or a carboxylic acid to act on a 4-halogenomethyl-1,3-dioxolane, prepared by acetalating a halogeno-1,2-propanediol represented by formula (1) (wherein X represents a halogen atom) in the presence of an acid catalyst, to conduct esterification or etherification and hydrolyzing the ester group and hydrogenolyzing the ether group to prepare a 1,3-dioxolane-4-methanol compound represented by formula (2) (wherein R?1 and R2¿ represent each hydrogen, an alkyl group having 1 to 4 carbon atoms, or a phenyl group, or R?1 and R2¿ together with the adjacent carbon atom may form a three- to six-membered ring. |
