a wide variety of
homoallylic alcohols in moderate to good yields with good levels of
enantioselectivities by combination of complementary ligand
(
PyBox-1 or PyBox-3) and solvent (CH Cl or CHCl ). The allylation

operation, environmentally friendly property, inexpensive and
readily available reagents. It extends the applications of rare-earth
metal compounds as catalysts in organic synthesis.
