- Reaction Between o-Diamino-1,2,6-thiadiazine 1,1-Dioxides and Aldehydes to Give Fused Imidazo and Pyrazino Derivatives
-
Reaction between 3,4,5-triamino-1,2,6-thiadiazine 1,1-dioxide and aldehydes, in acetic acid or DMF, under anhydrous conditions, leads to a mixture of imidazo- and pyrazino-1,2,6-thiadiazine derivatives.The ratio of both compounds depends on the nature of the aldehyde used.The same reaction, in the absence of solvent, affords only pyrazinothiadiazine derivatives.The uv, 1H-and 13C-nmr data of the new compounds are reported.
