This paper describes a Rh(I)-catalyzed highly efficient and enantioselective 1,2-addition of arylboronic acids to α-diketones with the use of a simple sulfur-alkene hybrid ligand. With as low as a 0.1 mol % catalyst loading, a variety of optically active α-hydroxyketones

Iridium complexes show high catalytic activity in intermolecular additions of acid chlorides to terminal alkynes to afford valuable (Z)-β-chloro-α,β-unsaturated ketones. Ligands in the catalytic system play a crucial role in this reaction. An N-heterocyclic carbene (NHC) is an efficient ligand

Cascade reactions: A modular assembly of azabicycles by using a cascade cyclization/Suzuki coupling/6π-electrocyclization of bromoenynamides is reported. The reaction offers a wide substituent scope on the bicyclic aminodiene products, which can be selectively oxidized as a general approach to aromatic
