Divergent reactivity: Various ethynylaziridines behave as strained propargyl amines and can be directly converted into unprotected α‐amino allenes by a highly diastereoselective SN2′ hydride delivery (see scheme). Additional reaction routes involve chemo‐ and regioselective transformation into either bicyclic aziridine/enol ethers or highly strained azirine alkynes.
不同的反应性:各种乙炔基氮丙啶表现为应变的炔丙基胺,可通过高度非对映选择性的S N 2'氢化物传输直接转化为未保护的α-氨基丙二烯(参见方案)。其他反应途径包括化学和区域选择性转化为双环氮丙啶/烯醇醚或高度紧张的叠氮炔。
