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 synthetic method provides a convenient and expeditious access to N-per(poly)fluoroalkanesulfonyl oxazolidines.
已开发出一种简便的一步法合成 2,3,5-三取代恶唑烷,通过酮、乙烯基醚和氟代烷磺酰叠氮化物在 0 摄氏度下的三组分反应,在 5 分钟内以中等收率进行合成。这种实用的合成方法为获得 N-per(poly)fluoroalkanesulfonyl oxazolidines 提供了方便快捷的途径。
