Timmer, Brian J. J. published the artcileAcid-Assisted Direct Olefin Metathesis of Unprotected Carbohydrates in Water, Product Details of C9H16O6, the main research area is disaccharide glycoside chelation galactopyranoside mannoside preparation olefin metathesis minimization; carbene ligands; carbohydrates; homogeneous catalysis; olefin metathesis; synthetic methods.
The ability to use unprotected carbohydrates in olefin metathesis reactions in aqueous media is demonstrated. By using water-soluble, amine-functionalized Hoveyda-Grubbs catalysts under mildly acidic aqueous conditions, the self-metathesis of unprotected alkene-functionalized α-D-manno- and α-D-galactopyranosides could be achieved through minimization of non-productive chelation and isomerization. Cross-metathesis with allyl alc. could also be achieved with reasonable selectivity. The presence of small quantities (2.5 vol %) of acetic acid increased the formation of the self-metathesis product while significantly reducing the alkene isomerization process. These results demonstrate the potential of directly using unprotected carbohydrate structures in olefin metathesis reactions under mild conditions compatible with biol. systems, and thereby enabling their use in, for example, drug discovery and protein derivatization.
