Hanessian, S.; Ponpipom, M. M.; Lavallee, P. published an article in 1972, the title of the article was Procedures for the direct replacement of primary hydroxyl groups in carbohydrates by halogen.Synthetic Route of 38838-06-1 And the article contains the following content:

Efficient halogenation of carbohydrates and certain nucleosides can be effected by treatment with Ph3P-N-halosuccinimide (bromo, chloro, or iodo). Groups commonly used in the protection of hydroxyl and amino functions are unaffected under the mild conditions of halogenation. Selective halogenation of hydroxymethyl groups in polyhydroxy compounds can be effected. The experimental process involved the reaction of (3aS,4S,6R,6aR)-4-(Iodomethyl)-6-methoxy-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxole(cas: 38838-06-1).Synthetic Route of 38838-06-1

On October 24, 1980, Binkley, Roger W.; Ambrose, Michael G.; Hehemann, David G. published an article.Application In Synthesis of (3aS,4S,6R,6aR)-4-(Iodomethyl)-6-methoxy-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxole The title of the article was Synthesis of deoxyhalogeno sugars. Displacement of the (trifluoromethanesulfonyl)oxy (triflyl) group by halide ion. And the article contained the following:

Deoxyhalo sugars were prepared by esterifying partially protected carbohydrates with triflic anhydride and reacting the resulting trifluoromethanesulfonates with tetrabutylammonium halides. This process for the preparation of halogenated carbohydrates is mild and convenient. It does not experience the difficulties, such as mol. rearrangement and lack of reactivity at secondary carbons, which sometimes are encountered in displacement reactions in carbohydrate systems. The experimental process involved the reaction of (3aS,4S,6R,6aR)-4-(Iodomethyl)-6-methoxy-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxole(cas: 38838-06-1).Application In Synthesis of (3aS,4S,6R,6aR)-4-(Iodomethyl)-6-methoxy-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxole

On December 4, 1981, Ariatti, Mario; Zemlicka, Jiri published an article.Quality Control of (3aS,4S,6R,6aR)-4-(Iodomethyl)-6-methoxy-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxole The title of the article was Reaction of carbohydrate halides with magnesium. Novel carbon-carbon coupling of sugar derivatives via organometallic intermediates. And the article contained the following:

The reaction of 3-deoxy-3-C-(iodomethyl)-1,2:5,6-di-O-isopropylidene-α-D-allofuranose (I) with sublimed Mg in refluxing THF gave dimer II and only traces of the 3-deoxy-3-Me derivative Similarly, Me 5-deoxy-5-iodo-2,3-O-isopropylidene-β-D-ribofuranoside (III) afforded the 5-5′-coupled compound, and 6-deoxy-6-iodo-1,2:3,4-di-O-isopropylidene-α-D-galactopyranose yielded the 6-6′-joined derivative The interaction of I with III gave the unsym. product in addition to the corresponding 2 sym. dimers. Dimer formation was also predominant in reaction of I with Mg in the presence of compounds such as PhCN or N-phthaloyl-L-phenylalanine 2-pyridine-2-thiol ester, which otherwise effectively trap the Grignard reagents. 5′-Deoxy-5′-iodo-2′,3′-O-isopropylidene-N3-methyluridine (IV) gave neither dimer nor the Grignard reagent. In addition, the dimer formation from I was inhibited in the presence of IV. II resulted also from the reaction of I with BuLi in THF whereas the interaction of the bromo analog of I produced only the 3-deoxy derivative The experimental process involved the reaction of (3aS,4S,6R,6aR)-4-(Iodomethyl)-6-methoxy-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxole(cas: 38838-06-1).Quality Control of (3aS,4S,6R,6aR)-4-(Iodomethyl)-6-methoxy-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxole

And the article contained the following:

Treatment of Me 5-deoxy-5-C-(diethoxyphosphinyl)-2,3-O-isopropylidene-β-D-ribofuranoside with Na dihydrobis(2-methoxyethoxy)aluminate, followed by H2O2, mineral acid, and H2O2, gave deoxy(hydroxyphosphinyl)ribopyranoses (I) in 40-45% overall yield. The structures of these sugar analogs were effectively established on the basis of the mass and 400-MHz, 1H-NMR spectra of the title compounds, derived by treatment with CH2N2 and then Ac2O in pyridine. The experimental process involved the reaction of (3aS,4S,6R,6aR)-4-(Iodomethyl)-6-methoxy-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxole(cas: 38838-06-1).SDS of cas: 38838-06-1

On September 30, 1979, Binkley, Roger W.; Hehemann, David G. published an article.Synthetic Route of 38838-06-1 The title of the article was Photolysis of deoxyiodo sugars. And the article contained the following:

Deoxyiodo sugars, prepared from the corresponding partially protected carbohydrates by the triflate displacement process, on photolysis for 3 h in Me2CHOH in the presence of NaHCO3 using 450-W medium pressure Hg lamp and a Corex filter gave the corresponding deoxy sugars in 72-100% yield. The choice of conditions for photolysis had a dramatic effect on the product yield, e.g., irradiation of I in MeOH using unfiltered light from an Hg lamp gave a mixture of products from which II was obtained in 32% yield, while irradiation in Me2CHOH and the use of Corex filter gave 100% II. The experimental process involved the reaction of (3aS,4S,6R,6aR)-4-(Iodomethyl)-6-methoxy-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxole(cas: 38838-06-1).Synthetic Route of 38838-06-1
