International audience; An straightforward approach wherein an excess of diisobutylaluminum hydride (DIBAL-H, 25.0 equiv), used as a molecular scalpel, is able to strip off three methyl groups from both primary and second faces of pemethylated α-cyc

Replacing the oxygen atom of the sugar ring with carbon is easy on paper, but it is more difficult to carry out this transformation and form five- and six-membered carbon rings (see scheme) in the flask. Nature has found a way to perform this tandem

Glycosyl cations are universally accepted key ionic intermediates in the mechanism of glycosylation, the reaction that covalently links carbohydrates to other molecules. These ions have remained hypothetical species so far because of their extremely

In our previous studies, a mechanism for DIBAL-H promoted regioselective bis-de-O-methylation of per-O-methylated cyclodextrin (CD) was proposed based on per-O-methylated β-CDs. As a further step to this work, four per-O-methylated α-CD derivatives

Diisobutylaluminium hydride (DIBAL-H) promotes secondary rim regioselective bis-de-O-methylation of permethylated β-cyclodextrin (β-CD) to give diol 2. To gain an insight into the mechanism of this remarkable regioselective behavior, two correspond

An unprecedented straightforward approach wherein an excess of diisobutylaluminum hydride is able to strip off in reasonable yield (45%) and in a regioselective manner four methyl groups from permethylated α-cyclodextrin, to provide a symmetric tetr

The conformational behaviour of the C-glycoside beta-C-Gal-(1-->3)-beta-Glc-OMe (1) has been studied using a combination of molecular mechanics and NMR spectroscopy (proton-proton coupling constants and nuclear Overhauser effects). It is shown that t
