In 2019,Chemistry – A European Journal included an article by Timmer, Brian J. J.; Ramstroem, Olof. Name: 5-Hexen-1-ol. The article was titled 《Acid-Assisted Direct Olefin Metathesis of Unprotected Carbohydrates in Water》. The information in the text is summarized as follows:
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. In the experimental materials used by the author, we found 5-Hexen-1-ol(cas: 821-41-0Name: 5-Hexen-1-ol)
5-Hexen-1-ol(cas: 821-41-0) is a volatile organic compound. Further, it is used to prepare 6-bromo-hex-1-ene by reaction with phosphorus tribromide.Name: 5-Hexen-1-ol
