The preparation of some hypervalent iodine reagents containing a transferable amino group derived from benzophenone imine derivatives is reported. The reagents can be readily prepared and stored as a bench‐stable solid, and were successfully used in the transition‐metal‐free oxidative amination of silyl ketene acetals to afford the corresponding α‐amino esters, the benzophenone imine moieties of which
据报道制备了一些含有衍生自二苯甲酮亚胺衍生物的可转移氨基的高价碘试剂。该试剂易于制备并以稳定的固体形式存储,已成功用于甲硅烷基酮缩醛的无过渡金属氧化胺化反应,得到相应的α-氨基酯,其二苯甲酮亚胺部分很容易水解,从而导致伯胺的形成。
