The synthesis of ethyl 2-[(2,2-dibenzoyl)ethenyl]amino-3- dimethylaminopropenoate and its application to the synthesis of fused 3- aminopyran-2-ones and 3-aminoazolo- and -azinopyrimidin-4(4H)-ones

Ethyl 2-[(2,2-dibenzoyl)ethenyl]amino-3-dimethylaminopropenoate (3) was prepared from dibenzoylmethane (1) in two steps, and used as a reagent for preparation of fused substituted 3-aminopyranones 12-15 in over 90% yield, quinolizin-4-one 16 in over 79% y

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.
