Abstract :
Application of new ligands (R)-(−)-8, (S)-(+)-16, and (S)-(+)-17 to the title reaction (1 or 2→3) led to excellent regio- and enantioselectivities (>30:1; ≤98% ee); although lacking the C2-symmetry, the catalysts can be viewed as quasi-C2-symmetrical since the single chiral center is sufficient to determine the sense of wrapping of the metal by the ligand.
