Application of Appel reaction to the primary alcohol groups of fructooligosaccharides: synthesis of 6,6â€?6′â€?trihalogenated 1-kestose derivatives was written by Tachrim, Zetryana Puteri;Nakamura, Tadashi;Sakihama, Yasuko;Hashidoko, Yasuyuki;Hashimoto, Makoto. And the article was included in ARKIVOC (Gainesville, FL, United States) in 2018.Electric Literature of C18H32O16 This article mentions the following:

1-kestose (O-β-D-fructofuranosyl-(2â†?)-β-D-fructofuranosyl-(2â†?)-α-D-glucopyranoside) is a potential short chain fructooligosaccharide with an inulin-type skeleton. Halogenation of 1-kestose was conducted via the Appel reaction with the use of carbon tetrahalide (CBr4 or CCl4) and triphenylphosphine, which was then followed by conventional acetylation. The per-O-acetylated form of 6,6â€?6′â€?trihalogenated derivatives of 1-kestose were conveniently isolated. Further deprotection of the per-O-acetylated form resulted in 6-, 6â€?, and 6′â€?trihalogenated derivatives The structure elucidation by one- and two-dimensional NMR established that halogenation are specific at the 6-, 6â€?, and 6′â€?position of 1-kestose primary alcs. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S,6R)-2-(((2S,3S,4S,5R)-2-((((2R,3S,4S,5R)-3,4-Dihydroxy-2,5-bis(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 470-69-9Electric Literature of C18H32O16).
