Novel Tsao Derivatives. Synthesis and Anti-HIV-1 Activity of Allofuranosyl-TSAO-T Analogues
摘要:
Novel TSAO-T analogues, in which the ribofuranosyl moiety has been replaced by an hexofuranosyl sugar moiety, have been prepared and evaluated for their inhibitory effect on HIV-1 replication in cell culture. In contrast to the prototype compound TSAO-T, the hexofuranosyl derivatives proved not active at subtoxic concentrations.

Abstract A procedure for the preparation of branched-chainsugars having highly functionalised C -branches is reported. Reaction of furanos-3-uloses, pyranos-3-uloses, or pyranos-2-uloses with sodium cyanide followed by mesylation of the corresponding cyanohydrin afforded α-mesyloxynitriles which, on treatment with base, underwent aldol-type cyclocondensation to yield furanose-3-spiro-, pyranose-3-spiro-
