(2R,3R,4R,5R)-2-(Acetoxymethyl)-5-(2,6-dichloro-9H-purin-9-yl)tetrahydrofuran-3,4-diyl diacetate (cas: 3056-18-6) belongs to tetrahydrofuran derivatives.Tetrahydrofuran has many industry uses as a solvent including in natural and synthetic resins, high polymers, fat oils, rubber, polymer. Tetrahydrofuran reaction with hydrogen sulfide: In the presence of a solid acid catalyst, tetrahydrofuran reacts with hydrogen sulfide to give tetrahydrothiophene.Formula: C16H16Cl2N4O7

Purine and 1-deazapurine ribonucleosides and deoxyribonucleosides: synthesis and biological activity was written by Cristalli, Gloria;Vittori, Sauro;Eleuteri, Alessandra;Grifantini, Mario;Volpini, Rosaria;Lupidi, Giulio;Capolongo, Laura;Pesenti, Enrico. And the article was included in Journal of Medicinal Chemistry in 1991.Formula: C16H16Cl2N4O7 This article mentions the following:

A series of 6-(hydroxyamino)purine and -1-deazapurine nucleosides, e.g. I (R = NHOH; R1 = Cl, H; R2 = H, tolyl; R3 = OH, H; Z = N, CH) were synthesized and tested for their antitumor and adenosine deaminase inhibitory activity. All compounds were comparable in activity to that of 6-(hydroxyamino)-9-β-D-ribofuranosylpurine and ara-A. Nucleoside I (R = NHOH, R1 = R2 = R3 = H, Z = CH), the less cytotoxic but the most active ADA inhibitor in the series greatly potentiates the antitumor activity of ara-A in vitro. In the experiment, the researchers used many compounds, for example, (2R,3R,4R,5R)-2-(Acetoxymethyl)-5-(2,6-dichloro-9H-purin-9-yl)tetrahydrofuran-3,4-diyl diacetate (cas: 3056-18-6Formula: C16H16Cl2N4O7).
