7a–c) derived from various primary amines and amino acid esters [glycine, (L)-alanine and (L)-phenylalanine] have been condensed with nitromethane in the presence of the rare-earth exchanged zeolite RE(70%)Na Y to give the S,N-acetals (5a–g, 8a–c). Mercuric chloride catalyzed hydrolysis of these (8a–c) has led to the nitroacetyl derivatives (9a–c). The glycine derivative (7a) gives a dimeric product

The efficient one-pot synthesis of several newtricyclic systems of type 1 and 2, obtained from the reaction of substituted 2-amino-3-cyanopyrroles and 3-amino-4-cyanopyrroles with BMMAs, is reported. The duration and yields of the reaction strongly depend on the reactivity of the starting pyrrole and on the size of the ring to be formed. Mechanist features of the reaction were investigated and proposed
