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

2-Alkoxy-2,5,5-trialkyl-Δ3-1,3,4-oxadiazolines (2), when photolyzed in solution with 300-nm light, afford the appropriate diazoalkane (3) and ester (4) in high yield.The diazoalkanes undergo intermolecular reaction, giving rise to azines (5), or they can be trapped in situ with 1,3-dipolarophiles to afford cycloadducts (7 or 11), which can in turn be photolyzed to the corresponding cyclopropenes (8) and cyclopropanes (12), respectively.
