Abstract
A simple and efficient method for the stereoselective synthesis of nojirimycin α-C-glycoside derivatives has been developed using a bicyclic carbamate-type sp2-iminosugar, whose preparation on a gram scale has been optimized, as the starting material. sp2-iminosugar O-glycosides or anomeric esters serve as excellent precursors of acyliminium cations, which can add nucleophiles, including C-nucleophiles. The stereochemical outcome of the reaction is governed by stereoelectronic effects, affording the target α-anomer with total stereoselectivity. Thus, the judicious combination of C-allylation, carbamate hydrolysis, cross-metathesis, and hydrogenation reactions provides a very convenient entry to iminosugar α-C-glycosides, which have been transformed into N,C-biantennary derivatives by reductive amination or thiourea-forming reactions. The thiourea adducts undergo intramolecular cyclization to bicyclic iminooxazolidine iminosugar α-C-glycosides upon acid treatment, broadening the opportunities for molecular diversity. A preliminary evaluation against a panel of commercial glycosidases validates the approach for finely tuning the inhibitory profile of glycomimetics.

Synthesis, conformational analysis and glycosidase inhibition of bicyclic nojirimycin C-glycosides based on an octahydrofuro[3,2-b]pyridine motif. Carbohydr Res 2021; 511:108491.

Abstract
A set of bicyclic iminosugar C-glycosides, based on an octahydrofuro[3,2-b]pyridine motif, has been synthesized from a C-allyl iminosugar exploiting a debenzylative iodocycloetherification and an iodine nucleophilic displacement as the key steps. The halogen allowed the introduction of a range of aglycon moieties of different sizes bearing several functionalities such as alcohol, amine, amide and triazole. In these carbohydrate mimics the fused THF ring forces the piperidine to adopt a flattened 4C1 conformation according to NMR and DFT calculations studies. In their deprotected form, these bicycles were assayed on a panel of 23 glycosidases. The iminosugars displaying hydrophobic aglycon moieties proved to be superior glycosidase inhibitors, leading to a low micromolar inhibition of human lysosome β-glucosidase (compound 11; IC50 = 2.7 μM) and rice α-glucosidase (compound 10; IC50 = 7.7 μM). Finally, the loose structural analogy of these derivatives with Thiamet G, a potent OGA bicyclic inhibitor, was illustrated by the weak OGA inhibitory activity (Ki = 140 μM) of iminosugar 5.

Abstract
![]()
A highly
efficient methodology of the preparation of synthetically
important tetrahydrofuran derivatives with an amino substituent in
the side chain is reported. This process is based on the stereocontrolled
debenzylative cycloetherification (DBCE) reaction applied for chirons
from the d-gluco- and d-manno-series and provides derivatives with new stereogenic
centers. The influence of the electron-withdrawing group (EWG), present
in the acyclic substrates with the mesyl leaving group, on the reactivity
in the DBCE reaction was investigated both “in the flask”
and by density functional theory (DFT) calculations. It was demonstrated
that tetrahydrofuran derivatives with the benzoxime group (EWG = CHNOBn)
are very good candidates for the subsequent highly stereoselective
Grignard reaction.
