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
