A novel highly enantioselective allyl-transfer reagent. Excellent regio-, diastereo-, and enantioselectivities are obtained for the addition of allyl nucleophiles to aldehydes.(1),(2),(3),(4) Though this reagent is used in stoichiometric amounts, the chiral ligand and monocyclopentadienyltitanium trichloride can be easily recovered.(5)
