How is 4-O-[3,4-Bis-O-(2-hydroxyethyl)-alpha-D-glucopyranosyl]-6-O-(hydroxymethyl)-2-O-{2-[2-hydroxy-3-(trimethylammonio)propoxy]ethyl}-beta-D-glucopyranose chloride (CAS: 81859-24-7) typically synthesized?

This compound can be synthesized through a series of reactions including glycosylation, acylation, and subsequent modifications. Commonly, a glucoside is reacted with a suitable acylating agent, followed by protection of the hydroxyl groups, and a final step to introduce the complex substituent. The reaction is typically carried out in the presence of a catalyst and under controlled conditions to achieve high yield and selectivity.
