The article summarizes the synthesis of two heterocycles linked by sulfur atom. The Friedlander reactions of 2-aminoarylketones with ketones 1, 4, and 7 have been explored, and three series of quinolines (3, 5, and 8) have been synthesized.

The cyclization of the derivatives of 3-aminotriazole, 2-(5-substituted 4H-1,2,4-triazol-3-ylamino)-1-arylethanones and 2-(4H-1,2,4-triazol-3-ylthio)-1-arylethanones to yield 6-aryl-4H-imidazo[1,2-b][1,2,4]triazoles and 6-aryl-thiazolo[3,2-b][1,2,4]triazoles has been described.

An efficient, regioselective C-5 arylation of thiazolo[3,2-b]-1,2,4- triazoles catalyzed by a simple copper catalyst was developed. This arylation proceeded smoothly and tolerated a variety of functional groups (44 examples). A wide range of functionalized thiazolo[3,2-b]-1,2,4-triazole derivatives were obtained in high yields (up to 99% yield). Possible catalytic cycles of the arylation were also discussed.
