Sly like a “DBFOX”: The chiral α‐hydroxy malonate 2 can be prepared in high yield and with up to 98 % ee from racemicmalonate 1 through α‐hydroxylation using oxaziridine 3 and is catalyzed by the (R,R)‐DBFOX‐Ph/NiII complex (see scheme). Biologically useful molecules have been prepared by using this method and illustrate its efficiency.
像“ DBFOX”一样狡猾:手性α-羟基丙二酸酯2可以高产率制备,外消旋丙二酸酯1通过恶唑烷3的α-羟基化反应可从外消旋丙二酸酯1中获得高达98% ee,并被(R,R)-DBFOX催化Ph / Ni II复合物(请参阅方案)。通过使用该方法已经制备了生物学上有用的分子,并说明了其效率。
