• Chemistry of Amino Acids. III. Reduction of Phenylalanine Ethyl Ester and Its Derivatives with Sodium Borohydride.
  作者：Hideo Seki、Kenji Koga、Shunichi Yamada

  DOI：10.1248/cpb.15.1948

  日期：——

  Eleven kinds of ethyl 2-substituted-3-phenylpropionates (Ia∼k) were reduced with sodium borohydride under a similar reaction condition and the effects of the α-substituents on the reduction were examined. Some esters (Ia∼c, e, f, j, k) were hydrolyzed with alkali. The obtained data of hydrolysis rate constants were roughly parallel to those of ester reductions. These results may be explained by considering both inductive and steric effects of the α-substituents.

  十一种乙基2取代-3-苯丙酸酯（Ia∼k）在相似的反应条件下被氢化钠还原，并考察了α-取代基对还原反应的影响。一些酯（Ia∼c, e, f, j, k）经过碱水解。获得的水解速率常数数据大致与酯的还原速率相平行。这些结果可以通过考虑α-取代基的诱导效应和立体效应来解释。
