A Convenient Synthesis of 1,2-Diazepino-quinoxalines via a 1,3-Dipolar Cycloaddition Reaction and Their Tautomeric Structure in a Solution

The reaction of the quinoxaline 4-oxides 7a,b with 2-chloroacrylonitrile resulted in the 1,3-dipolar cycloaddition reaction and further alteration to give the 4-hydroxy-2,3-dihydro-1H-1,2-diazepinoquinoxalines 8a,b and 9a,b, respectively, which were converted into the 4-oxo-2,3,4,6-tetrahydro-1H-1,2-diazepinoquinoxalines 10a,b-12a,b, respectively.The 2,3-dihydro-4-hydroxy form of 9a,b and the 2,3,4,6-trtrahydro-4-oxo form of 10a,b-12a,b were assigned by means of the NOE and 13C-nmr spectral data.

A Facile Synthesis of Novel 1,2-Diazepinoquinoxalines by a 1,3-Dipolar Cycloaddition Reaction

The 1,3-dipolar cycloaddition reaction of the quinoxaline 4-oxides 4a,b with 2-chloroacrylonitrile gave the 2,3-dihydro-1H-1,2-diazepinoquinoxalines 5a,b, respectively, which were converted into the 2,3,4,6-tetrahydro-1H-1,2-diazepinoquinoxalines 7a,b and 8a,b, respectively.
