A product of addition of diazomethane to the double bond of crotonolactone — Δ1-pyrazolinolactone — was obtained, and its isomerization to Δ2-pyrazolino-lactone in dry chloroform in the presence of triethylamine was studied. The structures of the compounds were confirmed by elementary analysis and the IR, UV, and PMR spectra.
