A practical and efficient two‐step procedure is reported for the preparation of a variety of α‐, β‐, γ‐ and δ‐amino acids from 2‐pyridone, 2‐pyrazinone or 2‐hydroxypyrimidine and derivatives. The procedure is amenable to scale‐up and in most cases no chromatographic purification of the product is required. This approach is useful, especially in the synthesis of amino acids or deuterated amino acids
据报道,从2-吡啶酮,2-吡嗪酮或2-羟基嘧啶及其衍生物制备各种α-,β-,γ-和δ-氨基酸的方法是实用,有效的两步程序。该程序适合扩大规模,在大多数情况下,无需色谱纯化产品。这种方法很有用,特别是在合成其他方法无法获得的氨基酸或氘代氨基酸时。
