✦ Synopsis
Optically pure 2-C-methyl-d-erythritol 4-phosphate, a key intermediate in the mevalonate-independent route for isoprenoid biosynthesis, is conveniently synthesized from 1,2-O-isopropylidene-a-d-xylofuranose, including the possibility of radiolabeling of this substrate.

Optically pure 1-deoxy-D-xylulose, a key metabolite for feeding experiments in the methylerythritol phosphate pathway for isoprenoid biosynthesis, is conveniently synthesised from 1,2-O-isopropylidene-a-D-xylofuranose or from D-arabinose. This renders labelling with hydrogen isotopes possible.
2-C-Methyl-D-erythritol 4-phosphate is a key intermediate in the mevalonate independent pathway for isoprenoid biosynthesis. In order to investigate the fate of the protons in this metabolic route, [3,5,5,5-2Ha]-2-C-methyl -D-erythritol was synthesized. The relevant steps allowing deuterium introduc
Free 2-C-methyl-d-erythritol is utilised for isoprenoid biosynthesis by Escherichia coli mutants lacking the two ®rst enzymes of the methylerythritol phosphate pathway, the deoxyxylulose phosphate synthase and isomero-reductase. For feeding experiments, this tetrol was synthesised with an overall 43
