Abstract
Serine hydroxymethyltransferase (SHMT) derived from recombinant E. coli was found to be able to catalyze the condensation between glycine and 4-pentenaldehyde, affording enantiopure l-erythro-2-amino-3-hydroxy-6-heptenoic acid (AHHA) in high yield and throughput. Conversion of this chiral intermediate of biosynthetic origin to the oral carbacephalosporin antibiotic loracarbef (Lorabid®) via β-lactam forming reactions and subsequent Dieckmann cyclization was achieved.
