摘要:A Novel Synthetic Route To 2-Deoxy-3,5-Di-O-P-Toluoyl-Alpha-L-Ribofuranosyl Chloride (1) From Inexpensive D-Xylose (3) Is Described. 1 Is A Key Intermediate In The Synthesis Of The Antiviral Agent 1-(2-Deoxy-Beta-L-Ribofuranosyl)Thymine (Beta-L-Thymidine) (2) And Other 2'-Deoxy-L-Ribonucleosides. This Seven-Step Synthesis Employs A Key Conversion Of The D To The L Configuration Of The Sugar Moiety (6 To 7 In Scheme 1) Using Simple Reagents And Reaction Conditions. The Entire Process Involves Only Three Isolation Steps. The Key Compound (1) Was Produced In 11% Overall Yield Without Chromatography.
