3'-Azido-2',3'-dideoxy-6-methyluridine (VIb) was prepared, together with its N3-isomer VIIb, by opening the 2,3'-bond in anhydronucleoside III with lithium azide in dimethylformamide and subsequent detritylation.The anhydro derivative III was synthesized from 2'-deoxy-6-methyl-uridine (I) by tritylation, mesylation and closure of the 2,3'-anhydro bond with 1,8-diazabicycloundec-7-ene.Dideoxy derivative XV was prepared by Barton deoxygenation of phenoxythiocarbonyl derivative IX followed by desilylation with tetrabutylammonium fluoride.Reduction of bis(phenoxythiocarbonyl) derivative XV with tributyltin hydride afforded 2',3'-dideoxy-2',3'-didehydro derivative XVI.The compound XV was obtained from arabinosyl derivative XIII which arises, along with 5,6-dihydro derivative XIV, by reaction of anhydronucleoside XII with lithium hydroxide in aqueous methanol.Desilylation of compound XVI with tetrabutylammonium fluoride resulted in quantitative removal of 6-methyluracil.
