摘要

Abstract The syntheses of enantiomer-enriched orthogonally protected different (2S)-2, 3- diaminopropanoates and unnatural furyl-substituted (tert-butoxy) carbonyl (Boc) as well as (benzyloxy) carbonyl (Cbz) protected amino acid esters are accomplished by means of an enantioselective aza-Henry reaction. A key feature of this protocol is organocatalysis as a genesis of chirality to ensure high enantioselectivity.
