described for the synthesis of bis(3-aryl-1-hexahydropyrimidinyl)methanes 1, by condensation of N-aryl-1,3-propanediarnines 2 with formaldehyde. The reaction mechanism involves N-arylhexahydropyrimidines 3 as intermediates. Such compounds can also be prepared efficiently by a methylene exchange reaction between bis-hexahydropyrimidines 1 and the corresponding diamines 2. The antimicrobial activity of compounds

A general procedure for regiospecific construction of N-aryl-N'-formyl-1,3-diaminopropanes 2 (R=H) by selective monoformylation of N-(3-aminopropyl)arylamines 1 is described. Compounds 1 are readily obtained with high yields by aminolysis of 3-bromopropylamine hydrobromide with aromatic amines. The present synthetic strategy was extended to the synthesis of other Nacyl-N'-aryl-1,3-diaminopropanes.
