213). 2 Synthesis of Protein Amino Acids and other Well-known Naturally Occurring Amino Acids. Thus, this Section is restricted to (a) biotechnological production of coded a-amino acids, and (b) synthesis of unusual a-amino acids. Reviews have appeared covering fermentative production of coded a-amino acids,224 l-alanine,225 l-lysine,226 l-threonine,227 and d-amino acids,228 enzymic production of l-threonine and l-allothreonine from 3-substituted 2-oxobutanoic acids using leucine dehydrogenase,229 d-phenylalanine and dtyrosine, also from corresponding a-keto acids but by a more roundabout route (glutamate racemase, d-amino acid transferase, glutamate dehydro- 1: Amino Acids 19 genase, formate dehydrogenase),230 and l-2-aminobutanoic acid (transamination from threonine or aspartic acid to 2-oxobutanoic acid by recombinant E.

250 All these amino acids have been synthesis targets in recent years, as have (7)-detoxinine [newly synthesized from l-ascorbic acid via (43)251], and (+)-furanomycin [prepared from l-xylose, with radical cyclization of (44) as a key step252]. Recognition of the importance of polyfunctional protein crosslinks (+)pyridinoline and its deoxy homologue has stimulated further exploration of routes for their synthesis (see Volume 30, p. 257 A synthesis of the pyridinium crosslink, pentosidine, from tert-butyl (2S)-2-(Bocamino)-6-iodohexanoate and an Nd-(imidazopyridyl)ornithine, has been described (see ref.

3 Synthesis of a-Alkyl a-Amino Acids ± The particular interest in a-methyl analogues of the coded l-amino acids has extended to more general types of structure under this heading (see also refs. 96, 99). The classical synthesis 22 Amino Acids, Peptides and Proteins routes (hydantoin and Bucherer-Bergs syntheses) have given good service for preparing racemic forms of these derivatives. 3) provide the main strategy. 4 Synthesis of a-Amino Acids Carrying Alkyl Side-chains, and Cyclic Analogues. ± The synthesis of `non-natural a-amino acids', most of which are designed either for their potential physiological activity or for use in peptide synthesis, is covered in this section if general synthesis methods are used for their preparation.
