New Pyrimidine Cyclonucleosides with Hydrogenated Aglycones: Synthesis and X-Ray Structures
摘要:
Acid catalysed transformations of (6S)-6,5'-anhydro-6-hydroxy-1-(2',3'-O-isopropylidene-beta -D-ribofuranosyl)hexahydropyrimidine-2-thione are studied. (6R)-6,2'-anhydro-6-hydroxy-1-(alpha -D-ribofuranosyl)hexahydropyrimidine-2-thione was formed as a thermodynamically stable product. Two intermediates, (6S)-6,5'-anhydro-6-hydroxy-1-(beta -D-ribofuranosyl)hexahydropyrimidine-2-thione and 6-hydroxy-1-(D-ribosyl)hexahydropyrimidine-2-thione and products of cleavage of glycosidic bond were identified in the reaction mixtures. Results of X-ray structural determination of the synthesised nucleosides are presented.
