enzymatic resolution of the corresponding racemic amino acid amide, giving access to the novel ligands (R)- and (S)-naphthylbis(oxazoline). Initial studies provided insight into the scope and limitations of the (S)-naphthyl-substituted bis(oxazoline) and its steric influence compared to other bis(oxazolines) in catalytic asymmetric synthesis.

通过酶促拆分相应的外消旋氨基酸酰胺,以 99% ee 获得 1-萘基甘氨酸的两种对映异构体,从而获得新的配体 (R)- 和 (S)-萘基双(恶唑啉)。初步研究提供了对 (S)-萘基取代的双 (恶唑啉) 的范围和局限性的深入了解,以及与催化不对称合成中的其他双 (恶唑啉) 相比的空间影响。(© Wiley-VCH Verlag GmbH & Co KGaA, 69451 Weinheim, Germany, 2003)
