Abstract An environmentally benign and economic synthesis of 1-[7-(1-benzyl-1 H-[1, 2, 3] triazol-4-ylmethoxy)-2, 2-dimethyl-chroman-6-yl]-3-aryl-2-propen-1-ones and 1-[5-(1-benzyl- 1 H-[1, 2, 3] triazol-4-ylmethoxy)-2, 2-dimethyl-chroman-6-yl]-3-aryl-propen-1-ones is described. The procedure takes place by the 1, 3-dipolar cycloaddition (''click-reaction'') between azides and alkynes catalysed by copper (I) salts. The simplicity of this reaction ...
