SYNTHESIS OF NOVELD- ANDL-3′-DEOXY-3′-C-HYDROXYMETHYL NUCLEOSIDE WITH EXOCYCLIC METHYLENE AS POTENTIAL RIBONUCLEOTIDE REDUCTASE INHIBITOR
摘要:
D- and L-3'-Deoxy-3'-C-hydroxymethyl thymidine substituted with exocyclic methylene at 2'-position were synthesized, starting from D- and L-xylose as potential ribonucleotide reductase inhibitor, respectively, but they were found to be inactive against several tumor cell lines.
L-Xylose was converted into a L-ribose derivative via an oxidation/reduction procedure. The L-ribosyl donor was submitted to a glycosidation reaction according to Vorbrüggen's conditions to give L-ribonucleosides (L-uridine, L-cytidine, L-adenosine and L-guanosine) in high yield.
