Biuret formyl

The common method of preparation of 6-alkyl-2,4-dioxotetrahydro-triazines is the cyclization of acyl-biurets by aqueous hydroxide. Formyl biuret which should by analogy 3deld 5-azauracil had not been known until recently. Its transient formation can be expected during further synthesis of 5-azauracil. Piskala and GuP achieved... [Pg.194]

Hydrolysis of the amidinium salt CXVII affords N-formyl biuret, which can be cyclized to dihydroxytriazine Thioureas and carbamates undergo a similar reaction with iminium chlorides... [Pg.86]
