The reaction of 2-(nitromethylene)imidazolidine (1) with olefins bearing an electron-withdrawing group gave Michael-type addition products and/or 5-nitro-1,7-diazabicyclo[4.3.0]nonane derivatives derived from the Michael-type adduct. The reaction of 1 with α,β-unsaturated aldehydes in the presence of an acid, on the other hand, gave similar diazabicyclic derivatives and 2-[(2-imidazolidinylidene)n
