| titleOfInvention | δ-Hydroxy-β-ketoester derivative and process for producing the same |
| abstract | Disclosed is a method for producing a δ-hydroxy-β-ketoester derivative and an optically active isomer thereof in a pure and economical manner. SOLUTION: General formula (4) (In the formula, R 1 represents a hydrogen atom, an alkyl group having 1 to 8 carbon atoms or an optionally substituted phenyl group. R 2 represents an alkyl group having 1 to 8 carbon atoms or an alkenyl group having 2 to 8 carbon atoms. Represents a C2-C8 alkynyl group or an optionally substituted phenyl group. X represents a halogen atom.) 2-halo-2-methyl-3-oxobutyric acid ester derivatives represented by Formula (5) R 3 CHO (wherein R 3 is a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, an alkenyl group having 2 to 8 carbon atoms, an alkynyl group having 2 to 8 carbon atoms, or optionally substituted) And an aldehyde represented by the formula (1) in the presence of a Lewis acid and a base. [Selection figure] None |
