An efficient synthesis of 3-fluoro-5-thio-xylofuranosyl nucleosides of thymine, uracil, and 5-fluorouracil as potential antitumor or/and antiviral agents
The synthesis and characterisation of a novel chiral bicyclic oxacaprolactone is reported. The choice of diisopropylidene-D-glucose as a starting material allowed selective introduction of the synthetic equivalent necessary for the formation of the seven-membered ring of the lactone, i.e., one
A practical route toward the synthesis of 6-deoxy-L-idose and L-acovenose from 1,2:5,6-di-O-isopropylidene-alpha-D-glucofuranose is described. Key steps include the stereoselective hydrogenation of 6-deoxy-1,2:3,5-di-O-isopropylidene-alpha-D-xylo-hex-5-enofuranose, regioselective protection of 6-deoxy-1,2-O-isopropylidene-beta-L-idofuranose at 0-5, and epimerisation of 6-deoxy-5-O-tert-butyldimethylsilyl-1,2-O-isopropylidene-beta-L-idofuranose at C-3.

Two sets of experimental protocols are given for the synthesis of 3',5'-bis-homodeoxyribonucleosides, building blocks for the synthesis of oligodeoxynucleotide analogs where the -O-PO2-O- groups are replaced by -CH2-S-CH2-, -CH2-SO-CH2-, and -CH2-SO2-CH2- units. Conditions are presented for joining these building blocks
