Electron-rich, electron-deficient, and non-activated alkenes can be rapidlyfunctionalized by in situ-generated difluoromethyl nitrile oxide. The (3+2) cycloaddition proceeds at room temperature, has broad functional group tolerance, and can be used for the late-stage modification of bioactive molecules (finasteride and carbamazepine). The obtained CF2H-isoxazolines can be easily transformed into CF2H-containing
