Efficient synthesis of exomethylene- and keto-exomethylene-D-glucopyranosyl nucleoside analogs as potential cytotoxic agents
(2011)
A novel series of exomethylene- and keto-exomethylene-D-glucopyranonucleosides with thymine, uracil, and 5-fluorouracil as heterocyclic bases have been designed and synthesized. Wittig condensation of the 3-keto glucoside ...
Branched-chain sugar nucleosides: stereocontrolled synthesis and bioevaluation of novel 3 '-C-trifluoromethyl and 3 '-C-methyl pyranonucleosides
(2015)
A new series of 3 '-C-trifluoromethyl- and 3 '-C-methyl-beta-D-allopyranonucleosides of 5-fluorouracil and their deoxy derivatives has been designed and synthesized. Treatment of ketosugar 1 with trifluoromethyltrimethylsilane ...
Stereocontrolled synthesis of 4 '-C-cyano and 4 '-C-cyano-4 '-deoxy pyrimidine pyranonucleosides as potential chemotherapeutic agents
(2012)
A new series of 4'-C-cyano and 4'-C-cyano-4'-deoxy pyrimidine pyranonucleosides has been designed and synthesized. Commercially available 1,2,3,4,6-penta-O-acetyl-D-mannopyranose (1) was condensed with silylated 5-fluorouracil, ...
