Using copper complexes with an axiallychiral bipyridine ligand C4-ACBP as the catalyst, an enantioselectivefunctionalization of indoles with diazo compounds was developed with up to 95% ee. This protocol paves the way for further applications of these ligands.

A method has been developed for the Pd-catalyzed synthesis of alpha-(hetero)aryl esters and amides through a Suzuki-Miyaura cross-coupling reaction. This method avoids the use of strong base, does not necessitate inert or low temperature formation of reagents, and does not require the use of a large excess of organometallic reagent. Utilization of organotrifluoroborate salts as nucleophilic partners allows a variety of functional groups and heterocyclic compounds to be tolerated.
