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
