The N-heterocyclic carbene (NHC)-catalyzed enantioselective kinetic resolution of anilides (a kind of hemiaminals) is reported. Upon exposure to the reaction in the presence of an NHC precatalyst and base, catalytic C–O bond formation occurs, providing axially chiral isoindolinones in high yields with excellent enantioselectivities.
该ñ N-杂环卡宾(NHC)催化苯胺的对映选择性动力学拆分(一种hemiaminals)的报道。在NHC预催化剂和碱的存在下暴露于反应中时,会发生催化C–O键形成,从而以高收率提供轴向手性异吲哚啉酮,并具有出色的对映选择性。
