A mild Rh-catalyzed method for synthesis of cyclic unprotected N–Me and N–H 2,3-aminoethers using an olefin aziridination–aziridine ring-opening domino reaction has been developed. The method is readily applicable to the stereocontrolled synthesis of a variety of 2,3-disubstituted aminoether O-heterocyclic scaffolds, including tetrahydrofurans, tetrahydropyrans and chromanes.
开发了一种温和的 Rh 催化方法,利用烯烃氮丙啶化-氮丙啶开环多米诺骨牌反应合成环状未保护的 N-Me 和 N-H 2,3-氨基醚。该方法易于适用于多种2,3-二取代氨基醚O-杂环支架的立体控制合成,包括四氢呋喃、四氢吡喃和苯并二氢吡喃。
