tert-Butyl cinnamates are aziridinated with high trans-selectivity by an N-N ylide generated in situ from N-methylmorpholine and O-diphenylphosphinyl hydroxylamine. The resulting N-unfunctionalised aziridines are shown to be versatile synthetic building blocks that undergo highly selective ring-opening reactions with a wide range of nucleophiles.
叔丁基肉桂酸酯在 N-甲基吗啉和 O-二苯膦基羟胺原位生成的 N-N 叶立德作用下以高反式选择性氮丙啶化。所得到的 N-未官能化氮丙啶被证明是多功能的合成砌块,可与广泛的亲核试剂进行高度选择性的开环反应。
