Highly diastereoselective Lewis acid induced intramolecular 1,3-dipolar cycloadditions of alkenyl phenylhydrazones (containing various substituents on the aromatic ring) obtained from a D-secopregnene aldehyde were carried out under fairly mild conditions

The phenylhydrazones of an unsaturated D-seco-pregnene aldehyde underwent BF3·OEt2-induced intramolecular 1,3-dipolar cycloaddition to afford new pyrazoline-fused Δ5-androstene derivatives under extremely mild conditions.
