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, ... -
Stereoselective facile synthesis of 2 '-spiro pyrimidine pyranonucleosides via their key intermediate 2 '-C-cyano analogues. Evaluation of their bioactivity
(2014)A novel series of 2'-spiro pyrimidine pyranonucleosides has been designed and synthesized. Their precursors, 2'-C-cyano nucleosides 5a,b and 6a,b, were obtained by subjecting 1a,b to the sequence of selective protection ...
