3,5-Di(hetero)aryl-substituted isoxazoles can be rapidly synthesized in a one-pot fashion by a consecutive three-component alkynylation–cyclization sequence starting from (hetero)aroyl chloride, alkynes, and sodium azide/acetic acid under copper-free palladium catalysis as exemplified by 9 different products.
