Reactions of β-aminoenones with acetylhydrazine, semicarbazide and methoxycarbonylhydrazine. Synthesis of 1-acetyl-, 1-carboxamide- or methyl 1- carboxylated pyrazole derivatives

Acetylhydrazine, semicarbazide and methoxycarbonylhydrazine react with β-aminoenones to give regioselectively the corresponding N-acetyl- or N- carboxypyrazole derivatives. The reaction are highly regioselective and occurs via 5-hydroxypyrazolines which in several case can be isolated and characterized.
