Two isomeric series of benzothieno-fused 7-deazapurine (benzo[4′,5′]thieno[3′,2′:4,5]- and benzo[4′,5′]thieno[2′,3′:4,5]pyrrolo[2,3-d]pyrimidine) ribonucleosides were designed and synthesized. Key steps of the synthesis included the Negishi coupling of zincated dichloropyrimidine with 2- or 3-iodobenzothiophene followed by azidation, thermal or photochem. cyclization, glycosylation, and final functionalization at position 6 through cross-couplings or nucleophilic substitutions. Deprotection gave the final nucleosides, some of which showed moderate cytotoxic and antiviral activity. Most of the free nucleosides showed moderate to strong fluorescence with emission maxima of 362-554 nm. 2′-Deoxyribonucleoside and its 5′-O-triphosphate were also prepared from benzothieno-fused 7-deazaadenine derivative, and the triphosphate was a good substrate for KOD XL DNA polymerase in primer extension synthesis of modified DNA which exerted a weak fluorescence which was slightly enhanced in double-stranded DNA as compared to single-stranded oligonucleotides. In the experiment, the researchers used many compounds, for example, 3-Iodobenzo[b]thiophene (cas: 36748-88-6Product Details of 36748-88-6).
3-Iodobenzo[b]thiophene (cas: 36748-88-6) belongs to iodide derivatives. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. Organoiodine lubricants can be used with titanium, stainless steels, and other metals which tend to seize up with conventional lubricants: organoiodine lubricants can be used in turbines and spacecraft, and as a cutting oil in machining.Product Details of 36748-88-6
