substituted fluorinated oxazolidines was achieved via a one-pot three-component reaction of fluoroalkanesulfonyl azides 1, vinyl ether 2 and various aldehydes at 0 °C within 10 min in moderate to good diastereoselectivities (syn/anti). A competing process could be involved in the initial step and an unstable fluorinated aziridine was postulated as the intermediate for these reactions. Additionally, rational
