**Chemically synthesized Ξ±βamino acids** are used to fortify foodstuffs and animal feeds. The drawbacks of former syntheses are avoided in the reaction sequence __(1)__β__(2)__β__(3)__ which leads, __e.g.__ to lysine in an overall yield of 52% (X ο£Ύ Cl, Br; R^1^ ο£Ύ Me, Et; M ο£Ύ K, Na, Li) equation ima
Enantioselective syntheses of optically active or-amino acids from glycine t-butyl ester through Schiff base employing (+)-N-alkyl-10-camphorsulfonamides as chiral auxiliaries were described. Methylation of Schiff base 5 gave high asymmetric inductions, whereas ethylation, allylation and benzylation
