Abstract
Abstract 2-C-Methyltetritols, or 2-methyl-1,2,3,4-butanetetraols, which exist as four stereoisomers, are found to be present in the atmosphere above the Amazonian rainforest. 2-C-methyl-d-erythritol was originally isolated from Convolvulus glomeratus and later synthesized enantiomerically pure. It has been claimed that these compounds are produced from isoprene by radical oxidation in the atmosphere. More recently, detailed analysis has shown that the mixture of stereoisomers from forests in both Brazil and Sweden contains unequal amounts of enantiomers. This shows that the oxidation must be due to enzymatic activity in plants. A review of the history of these compounds, synthesis and the significance of stereochemistry is given. Moreover, the significance of 2-C-methyl-d-erythritol for the non-mevalonate route to isoprenoids is briefly discussed.
