Journal ArticleDOI
Highly Efficient Chemoselective Deprotection of O,O-Acetals and O,O-Ketals Catalyzed by Molecular Iodine in Acetone
TL;DR: An extremely convenient method for deprotection of acetals and ketals catalyzed by molecular iodine in acetone is reported, and the highly acid-sensitive furyl, tert-butyl ethers, and ketone-oxime stayed intact.
Journal ArticleDOI
Highly efficient and versatile acetylation of alcohols catalyzed by cerium(III) triflate
Renato Dalpozzo,Antonio De Nino,Loredana Maiuolo,Antonio Procopio,Monica Nardi,Giuseppe Bartoli,Roberto Romeo +6 more
TL;DR: Cerium(III) triflate is a powerful catalyst for the acetylation of alcohols as discussed by the authors, which works well for a large variety of simple and functionalized alcohols, without isomerization of chiral centres.
Journal ArticleDOI
Highly regioselective ring opening of epoxides and aziridines using cerium(III) chloride
TL;DR: A wide variety of epoxides and aziridines were converted to the corresponding β-halohydrins and β-haloamines using cerium(III) chloride and the cerium-III chloride/NaI system in acetonitrile.
Journal ArticleDOI
CeCl3.7H2O: a novel reagent for the synthesis of 2-deoxysugars from D-glycals
TL;DR: In the absence of NaI, the glycals undergo Ferrier rearrangement under the influence of CeCl3·7H2O in refluxing acetonitrile to afford the corresponding 2,3-unsaturated hexopyranosides in good yields as mentioned in this paper.

Rapid chromatographic technique for preparative separations with moderate resolution
Abstract: (11) Potassium ferricyanide has previously been used to convert w'c-1,2-dicarboxylate groups to double bonds. See, for example, L. F. Fieser and M. J. Haddadln, J. Am. Chem. Soc., 86, 2392 (1964). The oxidative dldecarboxylation of 1,2-dlcarboxyllc acids is, of course, a well-known process. See Inter alia (a) C. A. Grob, M. Ohta, and A. Weiss, Helv. Chim. Acta, 41, 1911 (1958); and (b) E. N. Cain, R. Vukov, and S. Masamune, J. Chem. Soc. D, 98 (1969).

Reactions of carbonyl compounds with Grignard reagents in the presence of cerium chloride
TL;DR: The addition of Grignard reagents to ketones is significantly enhanced by cerium chloride with remarkable suppression of side reactions, particularly enolization.
