Synthesis of tamarixetin and isorhamnetin 3-O-neohesperidoside

Two isomeric flavonol 3-O-glycosides, tamarixetin and isorhamnetin 3-O-neohesperidoside (1 and 2), were synthesized. The natural product from Costus spicatus assigned as the former compound is revised to the latter structure.

Facile Synthesis of Ginsenoside Ro

Two concise synthetic routes, being different in the glycosylation sequence, toward ginsenoside Ro (1) are developed. These syntheses feature the elaboration of the glucuronide residue at a later stage via the TEMPO-mediated selective oxidation and the installation of AZMB as a benzoylic neighboring participating group capable of being selectively removed afterward.
