ENANTIOSPECIFIC SYNTHESIS OF POLYOXAMIC ACID FROM L-ARABINOSE

An enantiospecific synthesis of polyoxamic acid, 2-amino-2-deoxy-L-xylonic acid, by phenylthiolate opening of a five-carbon chiral hydroxylated aziridine easily derived from L-arabinose, is reported. The formation of the carboxyl group resulted from a Pummerer reaction
