We report herein a copper-catalyzed sequential multicomponent reaction of benzo[ d ]isoxazoles with terminal alkynes and sulfonyl azides, which produced divergent 4-amino-2 H -chromen-2-imines with excellent chemical selectivity. The reaction tolerated a broad range of functional groups, and released only N 2 as the sole byproduct. The sulfonyl imino group could be removed to give biologically active free 4-amino-2 H -chromenone in good yield.
