A new class of chiral oligothiophenes is described. Mono-, bi-, ter-, and quarterthiophenes have been linked to enantiopure trans-1,2-cyclohexanediamine (DACH) via diamino or diimino moieties. The stereochemistry of DACH, the type of linker, and oligothio

New efficient catalyst systems, coupled with IrCl(COD)PPh3 and chiral [SNNS]-type ligands, were employed in the asymmetric transfer hydrogenation of aromatic ketones under mild reaction conditions. The corresponding optically active alcohols we
Catalytic, enantioselective allylation of α-iminoesters promoted by silver(I) complexes of chiral imines

The catalytic enantioselective addition of allyltributylstannane to N-protected α-iminoesters promoted by silver(I) trifluoromethanesulfonate in the presence of chiral imine ligands was studied. After testing several chiral imines derived from 1,2-diamino
