Access to chiral tetrahydrofluorenes through a palladium-catalyzed enantioselective tandem intramolecular Heck/Tsuji-Trost reaction

Chem Commun (Camb). 2019 Mar 26;55(26):3769-3772. doi: 10.1039/c9cc01379b.

Abstract

A palladium-catalyzed enantioselective coupling of 2,5-cyclohexadienyl-substituted aryl iodides and carbon or heteroatom nucleophiles is described. The reaction proceeded via a tandem asymmetric Heck insertion and Tsuji-Trost allylation, enabling the rapid construction of valuable chiral tetrahydrofluorenes by using a chiral H8-BINOL-based phosphoramidite ligand.
