The Natural Amino Acid Derived Chiral Sulfonamide Ligands in the Catalytic Asymmetric Addition of Phenylacetylene to Aldehydes
Abstract:Several simple amino acids derived chiral sulfonamide ligands were synthesized in simple three steps. When we used these ligands in the asymmetric addition of phenylacetylene to aldehydes, the corresponding propargylic alcohols were isolated with good yields. The highest ee value was obtained up to 99%. The results proved that the backbone of the chiral source greatly influenced the enantioselectivity.
