The synthesis of substituted N-acetyl- and N-aroyl-2-pyrazolines via intramolecular Michael addition of α,β-unsaturated hydrazones generated through olefination of phosphinyl and phosphonyl hydrazones with carbonyl compounds is reported. The regioselective reduction of the C−N double bond in these 2-pyrazolines using Superhydride (Et3BHLi) gives pirazolidine derivatives with excellent levels of ci
