Multicomponent reactions provide efficient means to access molecular complexity. Herein, we report a copper‐catalyzed three‐component reaction of diazo compounds, alcohols and ethynyl benziodoxole (EBX) reagents for the synthesis of propargyl ethers. Extensive variations of the three partners of the reaction is possible, leading to highly functionalized and structurally diverse products under mild
