β-Arylation of Indanone Derivatives via α-Carbamoylation/Elimination of Isocyanate Sequence

β-Aryl carbonyl compounds are crucial motifs in pharmaceuticals and bioactive molecules, yet their synthesis from saturated carbonyl compounds remains a significant challenge. We report a practical and operationally simple protocol for β-arylation of cyclic carbonyl compounds, which seamlessly integrating with α-functionalization methods, enabling rapid, stereoselective construction of multi-substituted carbonyl compounds. The simplicity, broad applicability, and mechanistic insights provided by this β-arylation protocol establish it as a valuable tool for streamlined synthesis of complex carbonyl frameworks.
