Herein we present a highly efficient N-heterocyclic-carbene (NHC)-catalyzed atroposelective acylation of amino bisphenols to provide access to a wide range of 1,1′-biaryl-2,2′-amino alcohols (NOBIN analogs) in high yield and with uniformly excellent enantioselectivity. This catalytic system is shown to proceed through a combination of desymmetrization and secondary kinetic resolution to produce the axially
本文中,我们介绍了一种高效的N-杂环卡宾(NHC)催化的氨基双酚atroposelective酰化反应,以高产率提供广泛的1,1'-biaryl-2,2'-氨基醇(NOBIN类似物)并具有一致优异的对映选择性。已显示该催化体系通过脱对称和二级动力学拆分的组合进行,以产生具有优异对映选择性的轴向手性产物。
