4-aryl-2,4-dioxobutanoic acids and their derivatives in reactions with diazoalkanes

By treating 4-aryl-2,4-dioxobutanoic acids or their alkyl esters with diazomethane alkyl 4-aryl-2-methoxy-4-oxo-2-butenoates and 1-R-3-aroyl-4-methoxy-4-methoxycarbonyl-4,5-dihydropyrazoles were prepared. O-Alkyl derivatives and substituted pyrazoles were

Pyruvic Acid Dimethylhydrazone. A Synthetic Equivalent of the Pyruvic Acid Dianion

The pyruvic acid dimethyl hydrazone can be easily prepared in ether.This compound, after deprotonation with alkyllithium, forms a strong nucleophile which on tratment with electrophiles and acidic work up yield α-ketoacids, α-hydroxybutenolides or α,γ-diketoacids.
