Tiivistelmä
Anomeric 1-(3-deoxy-D-erythro-2-hexulofuranosyl)thymines and 9-(3-deoxy-D-erythro-2-hexulofuranosyl)adenines were prepared by tin(IV) chloride catalyzed N-glycosylation of trimethylsilylated thymine and N-6-benzoyladenine with methyl 3-deoxy-D-erythro-2-hexulofuranoside triacetate or tribenzoate, respectively. These O-glycosides used as starting materials were obtained by deoxygenation of 1,2: 4,5-di-O-isopropylidene-beta-D-fructopyranose and subsequent acid-catalyzed methanolysis of the resulting 3-deoxy derivative. The anomeric configuration of the nucleosides prepared was assigned by a combination of X-ray crystallography and 2D H-1 NMR spectroscopy. The conformation and hydrolytic stability of these new nucleoside analogous are discussed.
