Amino Acid Esters as Chiral Auxiliaries in Barbier-Type Reactions in Aqueous Solution
Waldmann, Herbert
, p. 1317 - 1322 (2007/10/02)
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
