Highly enantioselective arylation of aryl aldehydes catalyzed by (S)-H8-BINOL-Ti(Oi-Pr)2 complex in the presence of N-methylmorpholine (NMM) as an effective and inexpensive additive is described for the first time. We found high enan

A series of novel chiral benzimidazolium salts, the precursor of N-heterocyclic carbene ligands, were designed and synthesized from 1,2-dibromobenzene. In situ prepared corresponding carbenes were tested in asymmetric Rh-catalyzed arylation of aromatic aldehydes, affording chiral diarylmethanols with high yields and moderate enantioselectivities.

Figure Presented Cheap, energy-saving, and applicable: With the aid of AlCl3 and BDMAEE [2,2′-oxybis(N,N-dimethylethanamine)], a highly asymmetric catalytic addition of various aryl Grignard reagents to aldehydes was achieved under mild conditions with easily prepared (S)-H 8-BINOL and inexpensive commercially available Ti(OiPr)4 (see scheme), and the reaction could be easily scaled up with no loss of yield and enantioselectivity.
