2-Keto-3-deoxy-D-erythro-hexonic acid (KDG) is the key intermediate metabolite of the Entner Doudoroff (ED) pathway. A simple, efficient and stereoselective synthesis of KDG isopropyl ester is described in five steps from 2,3-O-isopropylidene-D-threitol with an overall yield of 47%. KDG isopropyl ester is studied as an attractive marker of a functional Entner Doudoroff pathway. KDG isopropyl ester is used to promote growth of ammonium producing bacterial strains, showing interesting features in the remediation of heavy-metal polluted soils.

A process has now been discovered by which an intermediate in preparation of antibiotics STR1 may be directly derived from the substrate STR2 by treatment with aqueous solutions of MHCO3 and MOH, wherein: R1, R2 and R3 are each independently alkyl, alkenyl, alkynyl, substituted alkyl, substituted alkenyl, substituted alkynyl, aryl, or substituted aryl; M is alkali metal (such as Na, Li, or K); and X is halogen.
