title: Highly enantioselective addition of phenylacetylene to aldehydes catalyzed by a camphorsulfonamide ligand.
abstract: The asymmetric addition of phenylacetylene to aldehydes was carried out by using a camphorsulfonamide titanium complex as a catalyst. The reactions proceeded under mild conditions and gave the products with good yields and high ees. This system is very useful for the synthesis of chiral propargylic alcohol. [reaction: see text]
