A green and convenient method for regioselective mono and multiple benzoylation of diols and polyols

An efficient method for regioselective benzoylation of diols and polyols was developed. The benzoylation is catalyzed by only 0.2 equiv of benzoate anion in acetonitrile with the addition of a stoichiometric amount of benzoic anhydride under very mild condition, leading to high yields. Compared with all other methods, this method shows particular advantage in regioselective multiple benzoylation of polyols, and in avoiding the use of any metal-based catalysts and any amine bases, which is more environment-friendly.

Facile oxidative cleavage of benzylidene acetals using molecular oxygen catalyzed by N-hydroxyphthalimide/Co(OAc)2

Benzylidene acetals derived from 1,2- and 1,3-diols undergo facile oxidative cleavage to give hydroxy benzoate esters with molecular oxygen in the presence of catalytic amount of N-hydroxyphthalimide/Co(OAc)2.

From methyl D-glucopyranoside to methyl D-allopyranoside via the Mitsunobu reaction

Methyl β-D-glucopyranoside reacted with a 4-molar excess of the Mitsunobu reagents (triphenylphosphine-diethyl azodicarboxylate-benzoic acid) under Weinges et al. [Carbohydr. Res., 164 (1987) 453-458] conditions to furnish four differently benzoylated methyl β-D-allopyranosides in a very good overall yield. The same reaction applied to methyl α-D-glucopyranoside yielded allosides in a low yield and nine other sugar products. These results give an insight into the course of the Mitsunobu esterification-inversion reaction. Copyright (C) 1999 Elsevier Science Ltd.

Reactions of Partially Acylated Aldohexopyranosides, II. - Regioselective Oxidation of Partially Acylated Aldohexopyranosides with Pyridinium Chlorochromate and a New Photochemical Method for the Preparation of Methyl 3,6-Dideoxy-α-D-ribo-hexopyranoside

Regioselective oxidation of methyl 2,6-di-O-pivaloyl-α-D-glucopyranoside (1) with pyridinium chlorochromate yields methyl 2,6-di-O-pivaloyl-α-D-ribo-hexopyranosid-3-ulose (2) as well as a ten-membered cyclic diester.If methyl 3,6-di-O-benzoyl- (7) and met

REGIOSELECTIVE O-DEACYLATION OF FULLY ACYLATED GLYCOSIDES AND 1,2-O-ISOPORPYLIDENEALDOFURANOSE DERIVATIVES WITH HYDRAZINE HYDRATE

On hydrazinolyis in 1:4 acetic acid-pyridine, and in pyridine, partisl O-deacylation of fully acylated methyl glycosides and some other glycosyl compounds ( 23 compounds ) was found to be induced, to give, in good yields, products bearing one free hydroxy
