| titleOfInvention |
4-fluoro-3-oxocarboxylic esters and process for producing the same |
| abstract |
The present invention is to provide 4-fluoro-3-oxocarboxylates represented by the following formula (1):wherein R1 represents an alkyl group or an aryl group;R2 and R3 each represent a hydrogen atom or an alkyl group;and R4 represents an alkyl group, and a process for preparing a 4-fluoro-3-oxocarboxylate represented by the above formula (1), which comprises allowing a 2-fluorocarboxylate represented by the following formula (2):wherein R1 and R2 have the same meanings as defined above;and R5 represents an alkyl group, to react with a carboxylate represented by the following formula (3):wherein R3 and R4 have the same meanings as defined above, in the presence of a base. |
