Tzeng, Cherng Chyi; Motola, Nancy C.; Panzica, Raymond P. published the artcile< Synthesis of certain 5,6-diamino-as-triazines: precursors for fused heterocyclic systems>, Safety of 6-Bromo-1,2,4-triazine-3,5(2H,4H)-dione, the main research area is triazine diamino derivative; triazinedione amino thiation; thiation aminotriazinedione.
An improved synthesis of 6-amino-as-triazine-3,5-dione (I, X = X1 = O) and selective thiation of this heterocycle provides two key intermediates I (X = O, X1 = S; X = X1 = S). Methylation of I (X = O, X1 = S; X = X1 = S) under basic conditions leads to their methylthio analogs, which on treatment with methanolic NH3 furnish 5,6-diamino-as-triazin-3-one and 5,6-diamino-3-(methylthio)-as-triazine, resp., in good overall yield.
Journal of Organic Chemistry published new progress about 4956-05-2. 4956-05-2 belongs to class pyrimidines, and the molecular formula is C3H2BrN3O2, Safety of 6-Bromo-1,2,4-triazine-3,5(2H,4H)-dione.
