synthesised (up to 77% ee) via a chiral tertiary amine-promoted nucleophilic aziridination of α,β-unsaturated ketones utilising in situ generated N–N ylides (aminimines). A wide range of chiral tertiary amines were synthesised and evaluated, allowing structure–activity relationships to be drawn. The most efficient promoter for asymmetric aziridination, quinine, was assessed with several enones to ascertain
通过手性叔胺促进的α,β-不饱和酮的手性叔胺促进的亲核叠氮反应,利用原位生成的N - N酰基化物(氨基胺)合成了反式N-未取代的氮丙啶(至多77%ee )。合成并评估了多种手性叔胺,从而可以得出结构-活性关系。用几种烯酮评估了不对称叠氮化的最有效启动子奎宁,以确定底物结构对产物ee的影响,而中间肼盐则通过X射线晶体学表征。
