In explorations of syntheses and chemistry of spiroheterocycles, we found that the reaction of 2-diazopropane with (E)-α-arylidenepyrrolin-2-one, (E)-α-arylidene-γ-butyrolactone, and (E)-arylidene-N-arylsuccinimide derivatives produced spiro-Δ1-p

The reaction of diphenyldiazomethane with N-substituted maleimides produces Δ1-pyrazolines. The photolysis of Δ1-pyrazolines leads to cyclopropanes.

The 1,3-dipolar cycloaddition of 2-diazopropane 1 with N-arylcitraconimides and N-arylmaleimides 2, at −78°C, has led to monoadducts 3. The same addition of 2-diazopropane with maleimide 4, has led to a new and unexpected Δ3-1,3,4-oxadiazoline 5.

Addition of diazopropane (II) to α-arylidenepyrrolidinones and α-arylidene-γ-butyrolactones (I) affords the monoadducts (III) in a regiospecific fashion.
