| (R,R)-DUTHALER-HAFNER REAGENT Usage And Synthesis |
| Uses | A novel highly enantioselective allyl-transfer reagent. Excellent regio-, diastereo-, and enantioselectivities (usually >95% ee, >95% de) are obtained for the addition of allyl nucleophiles to aldehydes. Although this reagent is used in stoichiometric amounts, the chiral ligand and monocyclopentadienyltitanium trichloride can be easily recovered. |
