GRAPHICAL ABSTRACT ABSTRACT Crown ethers possessing an external chain are called lariatethers. Huisgen cycloaddition is the 1,3-dipolar cycloaddition occurs between a suitable azide and terminal alkyne to give a stable 1,2,3-triazole system. It is the most common reaction of the so called philosophy of “click chemistry,” introduced by Nobel prize laureate Sharpless.

The efficient synthesis of new sulfur-containing macrocycles via click-type alkyne-azide cycloaddition was described. Preliminarily, under aqueous conditions (water-methanol) using CuSO4/sodium ascorbate as a source of Cu(I), the yields of the products were very poor. Using the Cu(I) in nonaqueous solution (MeCN), the yields of the products grow significantly (approx. 50%).
