D-Phg-L-Pro Dipeptide-derived prolinol ligands for highly enantioselective Reformatsky reactions
Shin, Eun-Kyoung,Kim, Hyun Jung,Kim, Yongtai,Kim, Yangmee,Park, Yong Sun
, p. 1933 - 1935 (2006)
Optically pure N-aminoethyl prolinol derivatives 3a-c have been prepared from the dynamic kinetic resolution of N-(α-bromo-α-phenylacetyl) proline ester 1 in asymmetric nucleophilic substitution and subsequent reduction. The peptide-derived prolinols are
Asymmetric dehydration of β-hydroxy esters and application to the syntheses of flavane derivatives
Choi, Eui Ta,Lee, Min Hee,Kim, Yongtae,Park, Yong Sun
, p. 1515 - 1522 (2008/09/18)
Catalytic asymmetric dehydration of β-aryl or alkyl substituted β-hydroxy esters via kinetic resolution has been investigated. A brief survey of 10 different chiral ligands is conducted to examine the effects of chiral ligand structure on selectivity of t
