An efficient synthesis of 3-fluoro-5-thio-xylofuranosyl nucleosides of thymine, uracil, and 5-fluorouracil as potential antitumor or/and antiviral agents
(2007)1,2:5,6-Di-O-isopropylidene-alpha-D-glucofuranose by the sequence of mild oxidation, reduction, fluorination, periodate oxidation, borohydride reduction, and sulfonylation gave 3-deoxy-3-fluoro-1,2-O-isopropylidene-5-O-p ... -
Exomethylene pyranonucleosides: Efficient synthesis and biological evaluation of 1-(2,3,4-trideoxy-2-methylene-beta-D-glycero-hex-3-enopyranosyl)thymine
(2007)A new series of unsaturated pyranonucleosides with an exocyclic methylene group and thymine as heterocyclic base have been designed and synthesized. D-Galactose (1) was readily transformed in three steps into the corresponding ... -
Fluoro-ketopyranosyl nucleosides: Synthesis and biological evaluation of 3-fluoro-2-keto-beta-D-glucopyranosyl derivatives of N-4-benzoyl cytosine
(2007)1,2:5,6-Di-O-isopropylidene-ot-D-glucofuranose on mild oxidation, reduction, fluorination, and deisopropylidenation followed by acetylation gave peracetylated 3-deoxy-3-fluoro-D-glueopyranose. This was coupled with silylated ... -
Synthesis and molecular modelling of unsaturated exomethylene pyranonucleoside analogues with antitumor and antiviral activities
(2008)This report describes the total and facile synthesis of the unsaturated keto and exomethylene pyranonucleoside analogues, 1-(2,3,4-trideoxy-4-methylene-6-O-trityl-alpha-D-glycero-hex-2-enopyranosyl)uracil (10), ... -
Unsaturated fluoro-ketopyranosyl nucleosides: Synthesis and biological evaluation of 3-fluoro-4-keto-beta-D-glucopyranosyl derivatives of N(4)-benzoyl cytosine and N(6)-benzoyl adenine
(2008)The protected beta-nucleosides 1-(2,4,6-tri-O-acetyl-3-deoxy-3-fluoro-beta-D-glucopyranosyl)-N(4)-benzoyl cytosine (2a) and 9-(2,4,6-tri-O-acetyl3-deoxy-3-fluoro-O-D-glucopyranosyl)-N6-benzoyl adenine (2b), were synthesized ...
