We have developed an efficientcopper-catalyzed method for the synthesis of the benzoxazoline-amidinederivatives. The protocol uses inexpensive copper(I) iodide as the catalyst, and furnished the expected product in good to excellent yields by a three-component reaction of sulfonyl azides, terminal alkynes and Schiffs’ bases in terahydrofuran (THF) at room temperature for 8 h in the presence of triethylamine
