(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. Tetrahydrofurans and furans are important oxygen-containing heterocycles that often exhibit interesting properties for biological applications or applications in the cosmetic industry. Tetrahydrofuran can also be produced, or synthesised, via catalytic hydrogenation of furan. This process involves converting certain sugars into THF by digesting to furfural. An alternative to this method is the catalytic hydrogenation of furan with a nickel catalyst.Category: tetrahydrofurans

Nucleic Acid Related Compounds. 118. Nonaqueous Diazotization of Aminopurine Derivatives. Convenient Access to 6-Halo- and 2,6-Dihalopurine Nucleosides and 2′-Deoxynucleosides with Acyl or Silyl Halides was written by Francom, Paula;Robins, Morris J.. And the article was included in Journal of Organic Chemistry in 2003.Category: tetrahydrofurans This article mentions the following:

Treatment of 9-(2,3,5-tri-O-acetyl-β-D-ribofuranosyl)-2-amino-6-chloropurine with TMS-Cl and benzyltriethylammonium nitrite (BTEA-NO2) in dichloromethane gave the crystalline 2,6-dichloropurine nucleoside I (R = OAc, X = Y = Cl), and acetyl chloride/BTEA-NO2 was equally effective (∼85%, without chromatog.). TMS-Br/tert-Bu nitrite/dibromomethane gave crystalline 2-bromo-6-chloro analog I (R = OAc, X = Br, Y = Cl) (85%). (Chloro or bromo)-dediazoniation of 3′,5′-di-O-acetyl-2′-deoxyadenosine gave chloro I (R = X = H, Y = Cl) (63%) or bromo I (R = X = H, Y = Br) (80%) purine deoxynucleosides, and 2′,3′,5′-tri-O-acetyladenosine was converted into the 6-chloropurine nucleoside I (R = OAc, X = H, Y = Cl) (71%). 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: 3056-18-6Category: tetrahydrofurans).
