How is (2S)-5-Hydroxy-2-(3-hydroxy-4-methoxyphenyl)-4-oxo-3,4-dihydro-2H-chromen-7-yl beta-D-glucopyranoside (CAS: 31712-49-9) typically synthesized?

This compound can be synthesized via a multistep process involving glycosylation of a chromen derivative. Commonly, the chromen is first protected, followed by a coupling reaction with the desired sugar moiety. The protecting group is then removed to yield the final compound. This synthesis typically involves the use of catalysts and solvents like acetic anhydride and acetic acid with controlled reaction conditions to ensure high selectivity and yield.
