construction of two categories of C–N atropisomers via rhodium(III)-catalyzed C–H activation of sulfoxonium ylides en route to [4+2] annulation with sterically hindered, electron-rich alkynes. This reaction proceeds with high regio- and enantioselectivity under redox-neutral conditions via a double-substrate activation strategy, providing a novel entry to C–N axially chiral 4-functionalized 1-naphthols
本文报道了两类 C-N 阻转异构体的有效和阻转选择性构建,方法是通过铑 (III) 催化的 C-H 活化锍叶立德在 [4+2] 环化过程中与空间位阻的富电子炔烃发生环化。该反应通过双底物活化策略在氧化还原中性条件下以高区域选择性和对映选择性进行,为 C-N 轴向手性 4-官能化 1-萘酚提供了新的途径。
