  Readily crystallized 2-C-methyl-D-ribono-1,4-lactone is formed in a one-pot procedure from D-glucose without any protecting groups by treatment with dimethylamine to give an Amadori ketose and then with aqueous calcium hydroxide in yields of approximately 25%; 2-C-methyl-L-ribono-1,4-lactone is similarly produced from L-glucose. 3,4-O-Isopropylidene-2-C-methyl-D-arabinono-1,5-lactone and 2-C-methyl-D-arabinono-1,4-lactone were prepared in a combined 60% yield by the Kiliani reaction of sodium cyanide with a protected 1-deoxy-D-ribulose derived from D-erythronolactone; the enantiomeric arabinonolactones are similarly available from L-erythronolactone.

• Towards the biotechnological isomerization of branched sugars: d-tagatose-3-epimerase equilibrates both enantiomers of 4-C-methyl-ribulose with both enantiomers of 4-C-methyl-xylulose

  Microbial oxidation of 2-C-methyl-D-ribitol and 2-C-methyl-D-arabinitol by Gluconobacter thailandicus NBRC 3254 produces 4-C-methyl-L-ribulose and 4-C-methyl-D-ribulose, respectively. Further, 4-C-methyl-L-ribulose and 4-C-methyl-D-ribulose were equilibrated by D-tagatose-3-epimerase (DTE) with 4-C-methyl-L-Xylulose and 4-C-methyl-D-XY11110se, respectively. These transformations demonstrate that polyol dehydrogenase and DTE act on branched synthetic sugars. The green preparation of all of the stereoisomers of 4-C-methyl pentuloses illustrates the ability of biotechnology to generate novel branched mono saccharides. (c) 2008 Elsevier Ltd.

  A series of novel sugar-modified derivatives of cytostatic 6-hetaryl-7-deazapurine ribonucleosides: 2′-C-methylribonucleosides, arabinonucleosides and 2′-deoxy-2′-fluoroarabinonucleosides bearing an alkyl, aryl and hetaryl group in position 6 were prepared by palladium catalyzed cross-coupling reactions of corresponding (protected) 6-chloro-(7-fluoro)-7-deazapurine nucleosides with (het)arylboronic, hetarylstannanes and trimethylaluminium eventually followed by deprotection. Key intermediate 6-chloro-7-deazapurine 2′-C-methyl-β-D-ribofuranoside was prepared via a stereoselective nucleobase anion glycosylation with toluoyl-protected 1,2-anhydro-2-C-methylribofuranose. The 1,2-anhydro sugar was synthesized in 3 steps starting from readily available 2-C-methylribonolactone. The 6-chloro-7-deazapurine arabinofuranoside intermediate was obtained by epimerization from 3′,5′-protected 6-chloro-7-deazapurine ribofuranoside via 2′-hydroxyl oxidation followed by reduction. None of the prepared compounds showed any considerable cytostatic or antiviral activity.
