多官能化芳烃是众多生物活性天然产物和药物中不可替代的一部分。过渡金属催化的直接不对称双或多CH键官能化是非常可取的,但探索较少。在此,我们开发了一种 Rh(III) 催化的不对称 C H 烯基化环化/酰胺化反应与带有O的烯烃系链芳烃的反应,能够在一个步骤中提供多种呋喃喹唑啉酮,具有广泛的底物范围和良好的官能团耐受性。
A Rh(III)-catalyzed twofold unsymmetrical C–H alkenylation–annulation/thiolation reaction has been developed, enabling the straightforward and efficient synthesis of various thiobenzofurans in one step. This robust protocol proceeds with a broad substrate scope and good functional group tolerance under relatively mild reaction conditions.

herein is a chiral sulfoximine-enabled Ru(II)-catalyzed asymmetric C–H activation/functionalization involving intramolecular hydroarylation and functionalization/annulation of alkynes. This process constructs dihydrobenzofuran- or indoline-fused isoquinolinones having a tertiary or quaternary stereocenter with good yields and enantioselectivities (up to 97:3 enantiomeric ratio). The chiral sulfoxide
