Article abstract of DOI:10.1016/0040-4020(92)85008-3

The 1,3-dipolar cycloaddition of nitrile oxides and a nitrone to alkylidencyclopropanes 1-5,used as model for methylenecyclopropanes substituted with aryl group (1), electron-releasing groups (2 and 3) and electron-attracting groups (4 and 5) is reported.
