Chiral Monophosphorus Ligands for Asymmetric Catalytic Reactions

Chiral monophosphorus ligands are playing an important role for the recent advances in asymmetric catalysis. This review summarizes the latest progress in various asymmetric catalytic reactions with the employment of chiral monophosphorus ligands including asymmetric allylic substitution, asymmetric dearomative arylation, asymmetric Heck reaction, asymmetric cross-coupling, asymmetric C–H bond functionalization, asymmetric coupling of π systems, asymmetric addition, asymmetric hydrogenation, and asymmetric organocatalytic reactions. The new reactivity, selectivity, and reaction mechanism enabled by these chiral monophosphorus ligands are discussed.
