The synthesis of gracillin and dioscin: Two typical representatives of spirostanol glycosides

Two representative spirostanol saponins that have the typical structure for the sugar moiety, diosgenyl α-L-rhamnopyranosyl-(1→2)-[β-D-glucopyranosyl-(1→3)]- β-D-glucopyranoside (gracillin) and diosgenyl α-L-rhamnopyranosyl-(1→2)-[α-L-rhamnopyranosyl-(1→4)]- β-D-glucopyranoside (dioscin), were easily synthesized by a general approach. A procedure using guanidine for the selective deblocking of acetyl while retaining benzoyl protecting groups is described.
