Abstract

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%).
