A unique and efficient 2,2,2-trifluoroethanol-activated one-pot reaction of β-nitroenamines, secondary amines and aromatic aldehydes was developed under mild and convenient conditions. In the presence of 2,2,2-trifluoroethanol (TFEA), aromatic aldehydes w

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-diazabicyclononane 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--5-nitro-1,7-diazabicyclonon-5-ene derivatives.The reaction of 1 with saturated and aromatic aldehydes in the presence of hydrochloric acid gave 1,3-bis(2-imidazolidinylidene)-1,3-dinitropropane derivatives.The enhanced enaminic character of 1 is ascribable to the two electron-donating amino groups fixed in a five-membered ring.
