烯烃与 N-磺酰基 oxaziridines 的区域选择性和对映选择性氧化胺化由新型铁 (II) 双 (恶唑啉) 络合物催化。这个过程提供了恶唑烷产品,可以很容易地操作以产生高度对映体富集的游离氨基醇。该过程的区域选择性与从类似的铜 (II) 催化反应中获得的区域选择性互补。Thus, both regioisomers of enantioenriched 1,2-aminoalcohols can be obtained using oxaziridine-mediated oxyamination reactions, and the overall sense of regiochemistry can be controlled using the appropriate choice of inexpensive first-row transition metal catalyst
我们发现 N-磺酰基恶氮丙啶在铁盐存在下与范围广泛的烯烃反应得到 1,3-恶唑烷。该过程提供了获得 1,2-氨基醇的途径,其具有与我们实验室先前报道的铜催化氧化胺化产生的区域选择性相反的意义。Thus, either regioisomeric form of 1,2-aminoalcohols can easily be obtained from the reaction of oxaziridines with olefins, and the sense of regioselectivity can be controlled by the appropriate choice of inexpensive, nontoxic, first-row transition-metal catalyst.
