The title compound, C 12 H 14 N 6 , was synthesized via cyclocondensation of 5-guanidino-3-phenyl-1,2,4-triazole with acetone. Only one tautomeric form with the NH H atom vicinal to the methyl groups was observed in the crystal structure. The triazine ring adopts a flattened half-boat conformation.
## Abstract A novel synthesis of substituted thieno[3,2β__c__]azepinones is described. This new approach uses 5,5βdimethylβ1,3βcyclohexanedione (dimedone) as the starting material. Oxime intermediates are obtained in three steps from the aforementioned diketone. Using these intermediates, the title
