Research is concerned with the synthesis of compounds containing an unsymmetrial triazine ring, including compounds having unsymmetrical triazine rings with different structures or with substituents in the triazine or adjacent ring such as the following: (1) an unsymmetrical triazine resembling the triazine of toxoflavin, (2) a py rimido-as-triazine, in which the position of the rings in relation to toxoflavin is changed, (3) a pyrazolo-pyrimidine, and (4) a pyridino-as triazine.
