Regioselective synthesis of 4-aryl-3,4-dihydro-1,3,5-triazino2,1-a-isoindol-2-ones

摘要

The condensation of binucleophilic 3-amino-1-arylimino-1H-isoindoles with bifunctional 1-chloro-benzylisocyanates occurs regioselectively resulting in 3,4-dihydro-1,3,5-triazino2,1-aisoindol-2-one derivatives.The structures of the synthesized compounds were unambiguously established by NOE experiments.
