Reaction of 2-Dimethylaminomethylene-1,3-diones with Dinucleophiles. I. Synthesis of 1,5-Disubstituted 4-Acylpyrazoles

Reaction of open-chain and cyclic sym-1,3-diones with N,N-dimethylformamide dimethyl acetal gave, generally in high yield, a series of sym-2-dimethylaminomethylene-1,3-diones which reacted with phenylhydrazine and methylhydrazine to afford, generally in satisfactory yield, a number of 1,5-disubstituted 4-acylpyrazoles.The applications and limits of this new pyrazole synthesis are presented and discussed.
