Abstract
PURPOSE:To obtain an optically active carbonyl compound enantio-selectively, by reaction between a beta-ketoacid and an optically active terpene compound followed by alkylation or the like of the product. CONSTITUTION:A beta-ketoacid, its derivative thereof such as beta-ketoacid tert.-butyl ester or its equivalent compound such as formyldramic acid is allowed to react with an optically active terpene such as 1-menthone to introduce an optically active group in the 2-position to give a chiral 1,3-dioxine-4-one having an optically active cyclic structure of the formula (X is optically active group originating from the terpene; Y, Z are H, lower alkyl, acyl). Then the product is subjected to alkylation reaction or catalytically hydrogenation in the presence of a reduction catalyst such as Pd/C or photoreaction to give an optically active carbonyl compound such as (R)-3-hydroxybutyric acid enantio-selectively.
