Анелювання 1,2,4-триазинового ядра до 2,3-бензодіазепіну
A one-pot, stepwise method for the annelation of the 1,2,4-triazine core to the seven-membered 2,3-benzodiazepine ring via the interaction of the corresponding 2,3-benzodiazepin-1-yl- or 2,3-benzodiazepin-4-ylhydrazines with α-ketoesters has been developed. It has been found that a stepwise formatio...

Journal of Organic and Pharmaceutical Chemistry| Резюме: | A one-pot, stepwise method for the annelation of the 1,2,4-triazine core to the seven-membered 2,3-benzodiazepine ring via the interaction of the corresponding 2,3-benzodiazepin-1-yl- or 2,3-benzodiazepin-4-ylhydrazines with α-ketoesters has been developed. It has been found that a stepwise formation of an azomethine intermediate followed by solvent replacement and subsequent cyclization enables the desired compounds to be obtained in high yields. Derivatives of a new heterocyclic system of [1,2,4]triazino[3,4-a][2,3]benzodiazepine have been synthesized. |
