THE CHIRAL LIGAND-CATALYZED ENANTIOSELECTIVE CONJUGATE ADDITION OF ORGANOLITHIUM TO BHA ENOATE
The conjugate addition reaction of BHA alkenoates with butyl- and phenyllithiums in toluene at -78°C were catalyzed by a substoichiometric amount of chiral ligands 1 and 2 to give the corresponding 3-substituted alkanoates in good to modest ees.
