Rapid, clean, and mild O-acetylation of alcohols and carbohydrates in an ionic liquid was written by Forsyth, Stewart A.;MacFarlane, Douglas R.;Thomson, Robin J.;von Itzstein, Mark. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2002.Formula: C28H38O19 This article mentions the following:
Archetypal O-acetylation reactions of alcs. and carbohydrates proceed rapidly in high yield under mild conditions in a dicyanamide based ionic liquid, that is not only an effective solvent but also an active base catalyst. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (cas: 126-14-7Formula: C28H38O19).
(2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (cas: 126-14-7) belongs to tetrahydrofuran derivatives. Tetrahydrofuran (THF), or oxolane, is mainly used as a precursor to polymers. Being polar and having a wide liquid range, THF is a versatile solvent. Oxidations have also proved to be valuable and efficient approaches to chiral tetrahydrofuran derivatives.Formula: C28H38O19
