Pd-catalyzed asymmetric dearomative arylation of C3-substituted indoles is realized via a desymmetrization strategy. A BINOL-derived chiral phosphoramidite ligand is found to be highly efficient for the stereoselective control in this reaction. This

Fluorine-containing molecules have attracted much attention in medicinal, agrochemical, and materials sciences because they offer unique physical and biological properties. Therefore, many efficient fluorination reactions have been developed over the

A ring-opening fluorination of isoxazoles has been developed. By treating isoxazoles with an electrophilic fluorinating agent (Selectfluor®), fluorination followed by deprotonation leads to tertiary fluorinated carbonyl compounds. The present method

A Pd-catalyzed dearomative three-component C–C bond formation of bromoarenes with diazo compounds and malonates was developed. Various bromoarenes ranging from benzenoids to azines and heteroles were transformed to the corresponding substituted ali

Dearomative C–C bond formation of benzyl phosphates has been developed. In the presence of a palladium/PAr3 catalyst, benzyl phosphates reacted with allyl borates to generate the allylated product in a dearomative fashion. The resulting dearomatize
