A convenient route is reported for the synthesis of substituted 1,3,4-thiadiazolo[3,2-a]-1,3,5-triazine-5,7-diones and isoxazolo[2,3-a]-1,3,5-triazines. Condensation of the appropriately substituted 2-amino-1,3,4-thiadiazole and 3-aminoisoxazole with phenoxycarbonyl isocyanate provides the desired target compounds in fair yield.
据报道,合成取代的1,3,4-噻二唑[3,2-a] -1,3,5-三嗪-5,7-二酮和异恶唑[2,3-a] -1的简便方法, 3,5-三嗪。适当取代的2-氨基-1,3,4-噻二唑和3-氨基异恶唑与苯氧羰基异氰酸酯的缩合以合理的收率提供了所需的目标化合物。
