Condensation of dihydroxy acetone phosphate (DHAP) on new hydroxy-aldehydes catalysed by fructose-1,6-diphosphate aldolases provides two aldoketoses presumed intermediates in the biosynthesis of nojirimycin and mannojirimycin, as well as useful precursors for the chemical synthesis of these aminosugars and some analogues.
Use of aldolases in the synthesis of non-carbohydrate natural products. Stereoselective synthesis of aspicilin C-3—C-9 fragment
The C-3—C-9 main fragment of aspicilin was prepared via a fructose 1,6-diphosphate aldolase reaction. The same fragment was also synthesized by chemical transformation starting from D-arabinose. Key words: aldolase, aspicilin, arabinose, synthesis.
