catalyzed atroposelective Friedlander reaction was developed in which acetylacetone and a variety of 2′-substituted 2-aminobenzophenones were successfully employed to give optically active biaryl quinolines in good yields and with high enantioselectivities.

A visible light photosensitizing metal-organic cage was employed as an artificial enzyme-mimicking nanoreactor for the selective arylation of terminal olefins, giving rise to controllable syntheses of geometrically defined E- or Z-alkenes with benzonitrile as the turn on/off key.

The design and development of a novel class of chiral sulfur–olefin hybrid ligands with high synthetic feasibility are described. These new sulfoxide–olefin ligands showed excellent catalytic activities and enantioselectivities (up to 98% ee) in rhodium-catalyzed asymmetric 1,4-addition reactions of aryl boronic acids to α,β-unsaturated carbonyl compounds.
