Synthesis of Aziridine Adducts 5: A solution of N-propenoyl
(5R)-5-phenylmorpholin-2-one (3; 231 mg, 1mmol) and the requisite aryl azide (1.5 mol) in toluene was heated to reflux for 2–3 h until TLC analysis indicated the absence of dipolarophile. Solvent was removed under reduced pressure and the crude material was purified by flash column chromatography on silica, eluting with PE–Et2O (1:7) to furnish the compounds 5 as colourless solids.

Answer 1

合成氮丙啶加合物5 ：一种解决办法的N -丙烯
（ 5R ） - 5 - phenylmorpholin - 2 - 1 （ 3 ; 231毫克， 1mmol ）和必要的芳基叠氮（ 1.5摩尔）在甲苯回流加热2-3 h ，直到薄层色谱分析表明，由于缺乏dipolarophile 。溶剂被删除的压力下减少和原油的材料纯化闪存柱层析硅胶，洗脱用PE Et2O （一时07 ）提供的化合物5无色固体。
