An improved synthesis of the saponin, polyphyllin D was written by Li, B.;Yu, B.;Hui, Y.;Li, M.;Han, X.;Fung, K.-P.. And the article was included in Carbohydrate Research in 2001.HPLC of Formula: 10030-85-0 This article mentions the following:
Polyphyllin D, namely diosgenyl α-L-rhamnopyranosyl-(1,2)-[(α-L-arabinofuranosyl)-(1,4)]-β-D-glucopyranoside, was synthesized from diosgenyl-β-D-glucopyranoside in four steps and in 30% overall yield, taking advantage of regioselective pivaloylation and α-L-rhamnopyranosylation reactions. In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5S)-2,3,4,5-tetrahydroxyhexanal hydrate (cas: 10030-85-0HPLC of Formula: 10030-85-0).
(2R,3R,4S,5S)-2,3,4,5-tetrahydroxyhexanal hydrate (cas: 10030-85-0) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.HPLC of Formula: 10030-85-0
