The β,γ-unsaturated amino acids are versatile chiral building blocks and biologically interesting compounds. The asymmetric synthesis of β,γ-unsaturated amino acids presents a challenging task as these compounds are labile toward racemization as well as the undesirable double bond isomerization. An efficient, general and mild kinetic resolution with readily accessible and fully recyclable cinchona
β,γ-不饱和氨基酸是通用的手性构件和生物学上有趣的化合物。β,γ-不饱和氨基酸的不对称合成是一项具有挑战性的任务,因为这些化合物容易发生外消旋化和不希望的双键异构化。已开发出一种高效、通用且温和的动力学拆分方法,具有易于获取且可完全回收的金鸡纳生物碱催化剂,为研究光学活性 β,γ-不饱和氨基酸提供了可靠有用的方法。
