The enantioselective synthesis of the non-proteinogenic amino acids β-proline and nipecotic acids from their readily available nitriles is achieved in high enantiomeric excess by commercially available nitrilases. The presented procedure comprises not more than 4 steps, thus considerably reducing the multiple steps generally required. Amide formation is also observed for specific heterocyclic nitriles
非蛋白源性氨基酸β-脯氨酸和乳糜酸从它们容易获得的腈中的对映选择性合成是通过市售腈水解酶以高对映体过量实现的。提出的过程包括不超过4个步骤,因此大大减少了通常需要的多个步骤。对于特定的杂环腈,也观察到酰胺的形成。
