Amino Acid Esters as Chiral Auxiliaries in Barbier-Type Reactions in Aqueous Solution
Valine and proline benzyl ester are converted into the aliphatic and aromatic α-oxo amides 5 by activation of the respective α-oxo acid by means of N,N'-diisopropylcarbodiimide.The α-oxo amides 5 undergo Barbier-type reactions with differently substituted

Stereochimie de la reduction electrochimique d'α-cetoamides optiquement actives II. Electroreduction de benzoylformamides derives de la S(-)-proline
Electrochemical reduction of benzoylformamides derived from S-(-)-proline has been carried out at a mercury cathode in a buffered hydroalcoholic medium; quantitative formation of a mixture of the two epimers of the corresponding mandelamides is observed.D
