Regioselective synthesis of 4-aryl-3,4-dihydro-1,3,5-triazino[2,1-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-triazino[2,1-a]isoindol-2-one derivatives. The structures of the synthesized compounds were unambiguously established by NOE experiments.
