  • Title: Isoprenoid biosynthesis via the MEP pathway. Synthesis of (3,4)-3,4-dihydroxy-5-oxohexylphosphonic acid, an isosteric analogue of 1-deoxy-D-xylulose 5-phosphate, the substrate of the 1-deoxy-D-xylulose 5-phosphate reducto-isomerase.

    Abstract:
    (3,4)-3,4-Dihydroxy-5-oxohexylphosphonic acid, an isosteric analogue of 1-deoxy-D-xylulose 5-phosphate (DXP), was obtained in enantiomerically pure form from (+)-2,3--benzylidene--threitol by a seven-step sequence. This phosphonate did not affect the growth of. It did not inhibit the 1-deoxy-D-xylulose 5-phosphate reductoisomerase (DXR), but was converted by this enzyme into (3,4)-3,4,5-trihydroxy-3-methylpentylphosphonic acid, an isosteric analogue of 2-C-methyl-D-erythritol 4-phosphate. The enzyme was, however, less efficient with the methylene phosphonate analogue than with the natural substrate.
