Abstract
Several 5-N-alkyl and 5-N,N-dialkylcarbamoyl substituted analogues of the anti-human immunodeficiency virus (HIV) type 1 lead compound[1-[2‘,5’-bis-O-(tert-butyldimethylsilyl)-β-D-ribofuranosyl]-5-(N,N-dimethylcarbamoyl)-1,2,3-triazole]-3‘-spiro-5“-(4”-amino-1“,2”-oxathiole-2“,2”-dioxide) have been prepared and evaluated as inhibitors of HIV-1 replication. A new regiospecific synthetic procedure is described. The compounds were prepared by cycloaddition of the appropriate glycosylazide to 2-oxo-alkylidentriphenyl-phosphoranes, followed by treatment with primary or secondary amines, to yield, exclusively, 5-substituted 1,2,3-triazole-TSAO analogues. Several 5-substituted 1,2,3-triazole-TSAO derivatives proved to be potent inhibitors of HIV-1 replication with higher antiviral selectivity than that of the parent TSAO prototype.Keywords
