-
, (2008/06/13)
The present invention is to provide 4-fluoro-3-oxocarboxylates represented by the following formula (1): wherein R1represents an alkyl group or an aryl group; R2and R3each represent a hydrogen atom or an alkyl group; and R4represents 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 R1and R2have the same meanings as defined above; and R5represents an alkyl group, to react with a carboxylate represented by the following formula (3): wherein R3and R4have the same meanings as defined above, in the presence of a base.
6-(1-fluoroalkyl)-4-pyrimidones and processes for producing the same
-
Example 1, (2008/06/13)
The present invention is to provide a novel 6-(1-fluoroalkyl)-4-pyrimidone represented by the following formula (1): wherein R1represents an alkyl group; R2represents a hydrogen atom or an alkyl group; and R3represents a hydrogen atom, an alkyl group or a chlorine atom, which is important for a synthetic intermediate for aminopyrimidine derivatives which are useful as acaricides, fungicides or nematocides, and processes for producing the same.
