| titleOfInvention | Process for producing disubstituted β-ketoesters |
| abstract | PROBLEM TO BE SOLVED: To provide a production method capable of easily and efficiently synthesizing disubstituted β-ketoesters by an aqueous reaction that can be easily isolated from a by-product. SOLUTION: Formula (I) [Chemical 1] (In the formula, R 1 represents an alkyl group, a perhalogenoalkyl group, an aryl group, a heteroaryl group, an allyl group, an aralkyl group or an OR 2 group, and R 2 and R 3 each independently represent the following reaction conditions: And a β-ketoester or β-diester represented by the formula (II): [Chemical 2] (Wherein R 4 represents a hydrogen atom or a lower alkyl group, and R 5 represents a protecting group that is not completely eliminated or decomposed under the following reaction conditions) (α-lower alkyl) acrylic By reacting the acid ester with an aqueous alkaline solution in the range of 1 to 10 M, the formula (III) [Chemical 3] (Wherein R 1 to R 5 represent the same meanings as in formula (I) and formula (II)). [Selection figure] None |
