The titled compounds (3) were synthesized by the reaction of nitrile oxides with 1-azirines and also the reaction of aliphatic nitro compounds with dibenzoylmethane derivatives in the presence of acetyl chloride and sodium methoxide. The structure of 3 was established by single crystal X-ray analysis. A mechanism of the formation for 3 is proposed.
