Syntheses and Applications of 1,2,3-Triazole-Fused Pyrazines and Pyridazines
Pyrazines and pyridazines fused to 1,2,3-triazoles comprise a set of heterocycles obtained through a variety of synthetic routes. Two typical modes of constructing these heterocyclic ring systems are cyclizing a heterocyclic diamine with a nitrite or ...
