β3-Amino acids are key components of some pharmaceuticals, excellent surrogates for metabolically labile α-amino acids, and building blocks for chiral heterocycles. Unfortunately they are not easily accessible in enantiomerically pure form, especially when possessing unnatural side chains. A flexible, chromatography-free process for the synthesis of enantiopure β3-amino acids possessing natural and
β 3 -氨基酸是一些药物的关键组分,代谢不稳定的α氨基酸优良替代物,和用于手性杂环积木。不幸的是,它们不容易以对映体纯的形式获得,特别是当具有不自然的侧链时。用于合成的柔性,自由色谱过程对映体纯β 3 -氨基酸具有天然和非天然侧链进行说明。该方法使用廉价的起始原料和试剂,为对映纯α-氨基酸的危险且昂贵的Arndt-Eistert同源提供了很好的替代方法。它的效用已被证明与两种有价值β制备规模合成3 -氨基酸具有非天然侧链。
