Allylic azide rearrangement in tandem with Huisgen cycloaddition for stereoselective annulation: synthesis of C-Glycosyl iminosugars
Moynihan, Lorna; Chadda, Rekha; McArdle, Patrick; Murphy, Paul V. (American Chemical Society, 2015-12-09)Allylic azide rearrangement is used. in,tandem with. intramolecular azide-alkene cycloaddition to give a triazoline that when subsequently decomposed in the presence of a nucleophile gives piperidines. The tandem reaction ... -
Allylic azide rearrangement in tandem with intramolecular Huisgen cycloaddition for iminosugar and glycomimetic synthesis. Functionalized piperidine, pyrrolidine and pyrrolotriazoles from D-mannose
Chadda, Rekha; McArdle, Patrick; Murphy, Paul V. (Thieme Publishing, 2017-04-20)Intramolecular Huisgen azide-alkene cycloaddition reaction of 7-azido-hepta-1,5-diene-3,4-diols, prepared from methyl α-d-mannopyranoside, were carried out. Allylic azide rearrangement to secondary azides occurred ... -
Building blocks from monosaccharides for synthesis of scaffolds, including macrocycles. Application of allylic azide rearrangement, azide-alkyne cycloaddition and ring closing metathesis
Fox, Karen A.; Chadda, Rekha; Cardona, Francisco; Barron, Stephen; McArdle, Patrick; Murphy, Paul V. (Elsevier, 2020-09-18)Synthesis of compounds with characteristics of natural products are required to increase the diversity and biological relevance of compounds for screening. These include new frameworks/scaffolds, with multiple stereogenic ... -
A route to 1-Deoxynojirimycin and 1-Deoxymannojirimycin derivatives with quaternary centers adjacent to the ring nitrogen from Methyl α-d-Mannopyranoside
Chadda, Rekha; Murphy, Paul V. (Wiley, 2020-02-03)6-Alkylated-8-azido-1,6-octadiene derivatives were prepared from methyl α-D-mannopyranoside. The sequence to allylic azide precursors included a Horner-Wadsworth-Emmons reaction with a concomitant epimerization that ...
