A sequential phosphine-catalyzed asymmetric [3+2] annulation and oxidative central-to-axial chirality transfer strategy has been developed, allowing for rapid access to a range of axially chiral CF3-containing 2-arylpyrroles with high enantiomeric excess. The practicality of the method is also illustrated in the atroposelective synthesis of esaxerenone.
已经开发出连续膦催化的不对称 [3+2] 环化和氧化中心到轴向手性转移策略,允许快速获得一系列具有高对映体过量的轴向手性 CF 3 2-芳基
吡咯。esaxerenone 的转位选择性合成也说明了该方法的实用性。
