First total synthesis of 25(R)-ruscogenin-1-yl β-D-xylopyranosyl-(1→3)-[β-D-glucopyranosyl-(1→2)]-β-D-fucopyranoside, an Ophiopogonis saponin from the tuber of Liriope muscari (Decne.)

The first total synthesis of 25(R)-ruscogenin-1-yl β-D-xylopyranosyl-(1→3)-[β-D-glucopyranosyl-(1→2)]-β-D-fucopyranoside (1), an Ophiopogonis saponin with strong anti-inflammatory and immunopharmacological activities from the tuber of Liriope muscari (Decne.), is described. The glycosylation of a highly hindered alcohol by Schmidt's 'inverse procedure' is demonstrated.

Phytochemical analyses have been carried out on the fresh bulbs of Ornithogalum thyrsoides with particular attention to the steroidal glycoside constituents, resulting in the isolation of four new spirostanol saponins and seven new cholestane glycosides, together with three known steroidal compounds. The structures of the new glycosides were determined on the basis of their spectroscopic data, including 2D NMR spectroscopy, and the results of hydrolytic cleavage. The isolated compounds were evaluated for their cytotoxic activities against HL-60 human promyelocytic leukemia cells and HSC-2 human oral squamous cell carcinoma cells.
