On October 9, 1991, Barrett, Anthony G. M.; Melcher, Laura M. published an article.Recommanded Product: (3aS,4S,6R,6aR)-4-(Iodomethyl)-6-methoxy-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxole The title of the article was Tetraphenyl distibine: a most useful reagent for discriminating radical reactions. And the article contained the following:

6-Deoxy-6-iodo-1,2:3,4-di-O-isopropylidene-α-D-galactopyranose I (X = iodo) and (tetrahydro-2H-pyran-2-yl)methyl iodide reacted rapidly with Ph2SbSbPh2 on irradiation to give the air stable alkyl(diphenyl)stibines I (X = SbPh2) and RCH2SbPh2 (R = tetrahydro-2H-pyran-2-yl). In contrast, Me 5-deoxy-5-iodo-2,3-O-isopropylidene-β-D-ribofuranoside II (X = iodo) and (tetrahydro-2-furanyl)methyl iodide reacted only very slowly with Ph2SbSbPh2 under identical conditions to provide the very air sensitive stibines II (X = Ph2Sb) and RCH2SbPh2 (R = tetrahydrofuran-2-yl). Air oxidation of the latter gave Me 2,3-O-isopropylidene-β-D-ribofuranoside and tetrahydrofurfuryl alc. resp., whereas oxidation of I (X = SbPh2) using H2O2 I (X = OH). Lewis base coordination of diphenylantimony (II) [Ph2Sb•] is proposed to account for this highly selective radical chem. 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).Recommanded Product: (3aS,4S,6R,6aR)-4-(Iodomethyl)-6-methoxy-2,2-dimethyltetrahydrofuro[3,4-d][1,3]dioxole

Secrist, John A. III; Wu, Shang-Ren published an article in 1977, the title of the article was Generation and reactivity of an unstabilized carbohydrate phosphorane.Computed Properties of 38838-06-1 And the article contains the following content:

The ylide (I) of the phosphonioribofuranoside II was prepared by treating Me 5-deoxy-5-iodo-2,3-O-isopropylidene-β-D-ribofuranoside with Ph3P in sulfolane at 110° for several days and subsequent treatment with BuLi. Condensation of I with RCHO (R = Ph, 4-ClC6H4, 4-MeOC6H4, PhCH2CH2, Pr, Bu) gave the olefins III with α-L-lyxo conformations, resulting from epimerizatin of the ylide prior to reaction. Treating I with cationic Dowex 50 gave the self-condensation product IV. 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).Computed Properties of 38838-06-1

On July 6, 1990, Musicki, Branislav; Widlanski, Theodore S. published an article.Recommanded Product: 38838-06-1 The title of the article was Synthesis of carbohydrate sulfonates and sulfonate esters. And the article contained the following:

The reaction of α-lithio sulfonate esters with primary carbohydrates iodides provides a facile route to sulfonate analogs of important carbohydrate phosphates such as glucose 6-phosphate, ribose 5-phosphate, and uridine 5-phosphate. This method also facilitates the synthesis of complex sulfonate esters. Thus, reaction of Me glycoside I with Me2CHO3SCH2Li gave sugar II after deprotection.

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
