摘要
Phosphoramidite-derived copper(I) catalysts readily facilitate the enantioselective 1,4-addition of dialkyl zinc reagents to nitro acrylates. The resulting 2-substituted 3-nitro propionic acid esters can easily be transformed to beta(2)-amino acids. (C) 2003 Elsevier Science Ltd. All rights reserved.
