Enantioselective allylation of aldehydes catalyzed by chiral indium(III) complexes immobilized in ionic liquids

In the presence of chiral catalytic complexes prepared from In(OTf)3 and chiral PYBOX ligands, allytributylstannane reacted with aldehydes in ionic liquids to afford the corresponding homoallylic alcohols in high enantioselectivities (86–94% ee) and good yields (68 –89%); the chiral catalysts immobilized in ionic liquids could be reused with comparable enantioselectivities and yields.
