A facile one-step method has been developed for the synthesis of 2,3,5-trisubstituted oxazolidines in moderate yields by the three-component reaction of ketones, vinyl ethers, and fluoroalkanesulfonyl azides at 0 degrees C within five minutes. This practical syntheticmethod provides a convenient and expeditious access to N-per(poly)fluoroalkanesulfonyl oxazolidines.
