## Abstract A series of Ξ²βsulfonamide alcohol ligands were synthesized from Lβphenylalanine. Titanium complexes of these compounds were used to catalyze the asymmetric addition of phenylacetylene to a number of aldehydes. When the conditions were optimized, 20β molβ % of ligand **8a** catalyzed the r
