通过“点击化学”从叠氮甲基喹啉与不同炔烃中合成了一系列喹啉偶联的1,2,3-三唑化合物。Cu(I)催化的叠氮化物-炔烃反应的效率和保真度通过良好的收率和预期的1,4-二取代的三唑产物的排他性得以证实。通过荧光素酶报道噬菌体(LRP)测定,筛选所有合成的化合物针对结核分枝杆菌H37Rv的抗结核活性。喹啉偶联三唑糖杂化物20是该系列中最有效的化合物,根据相对光单位在5和25 cup / mL时的减少百分比计算,减少量分别为76.41%和78.37%。

Cu(II) salts accelerate azide-alkyne cycloaddition reactions in alcoholic solvents without reductants such as sodium ascorbate. Spectroscopic observations suggest that Cu(II) undergoes reduction to catalytic Cu(l) species via either alcohol oxidation or alkyne homocoupling, or both, during an induction period. The reactions involving 2-picolylazide are likely facilitated by its chelation to Cu(II). The highly exothermic reaction between 2-picolylazide and propargyl alcohol completes within 1-2 min in the presence of as low as 1 mol % Cu(OAC)(2).

A series of quinoline coupled 1,2,3-triazoles compounds have been synthesized by 'click chemistry' from azidomethyl quinoline with different alkynes. The efficiency and fidelity of the Cu(I)-catalyzed azide-alkyne reaction are substantiated by good yields and exclusive formation of the expected 1,4-disubstituted triazole product. All the synthesized compounds were screened for anti-tubercular activity
