Novel 4-substituted 4,5-dihydro-3H-(8-amino-6-oxo)pyrrolo[3,4-f][1,3,5]triazepines from(Z)-N2-(2-amino-1,2-dicyano)formamidine and carbonyl compounds
Abstract
The title formamidicine reacts with ArCHO (where Ar = Ph, 4-MeC6H4, 4-MeOC6H4, 4-FC6H4) and acetone in the presence of a base to give products, shown by X-ray crystallography (Ar = Ph), to be the title compounds 4a–e
