Abstract
The reaction of 2-(bromomethyl)benzonitrile with methyl 3-aminothiophene-2-carboxylate results in two tautomeric thienopyrimidoisoindolones. Their methylation yields 5-methylthieno[2',3':5,6]pyrimido[2,1-a]isoindol-4(5H)-one which reacts with N-substituted maleimides and dimethyl acetylenedicarboxylate.
