arylative dearomatization of β-naphthols is described. Using Q-Phos as a ligand, the arylative dearomatization reaction proceeded smoothly affording excellent yields and chemoselectivity even when the catalyst loading was reduced to 0.1 mol%. This method offers an efficient access to a series of structurally diverse spirocarbocycles. Preliminary investigation indicates that an enantioselective reaction

The palladium-catalyzed intramolecular dearomative Heckreaction of 2,3-disubstituted indoles serves as an access to spiro-indoline products. Herein, we report an efficient construction of indoline/indolenine core stuctures via a dearomative Heckreaction of simple 2,3-disubstituted indoles with all-carbon tethers and the subsequent aza-semipinacol rearrangement. The Heckreaction features a high C2-selectivity
