A novel ytterbium(III) trifluoromethanesulfonate [Yb(OTf)₃]‐catalyzed ring‐opening C(sp³)−N bond formation reaction of benzoxazole with propargylic alcohols was established. This reaction uses readily available starting materials and is operationally simple; it thus represents a practical method for the construction of highly functionalized substituted benzenes bearing aldehyde, propargylamine, and hydroxy groups with high atom economy.
