摘要

(2 S, 4 R)-2-Amino-4-hydroxyadipic acid (Ahad) building block 45 was synthesized in 11 steps and 6.5% overall yield from commercially available materials. Key steps in stereocontrol were an asymmetric conjugate addition employing a proline-based catalyst and a syn-selective intramolecular-conjugate addition of an oxygen nucleophile to an α, β- unsaturated ester. To enable incorporation of α-amino-adipic acid (α-AAA) and Ahad into ...
