Process for producing (S) -5-substituted-5-hydroxy-3-oxopentanoic acid ester derivatives |
| abstract |
PROBLEM TO BE SOLVED: To provide an (S) -5-substituted-5-hydroxy-3-oxopentanoic acid ester derivative with high optical purity and high isolation yield by a simple method. , Industrially suitable An object of the present invention is to provide a method for producing an (S) -5-substituted-5-hydroxy-3-oxopentanoic acid ester derivative. The object of the present invention is to react an aldehyde compound and a diketene in an organic solvent in the presence of an amine and a titanium complex obtained by reacting an optically active Schiff base with a titanium compound. , (S) -5-substituted-5- The problem is solved by a method for producing a hydroxy-3-oxopentanoic acid ester derivative. |
