Abstract :
An efficient five-step formal synthesis of osladin by utilizing the intact skeleton of diosgenin acetate is reported. Key features of this study include an unprecedented reductive opening of E-ring in steroidal sapogenin to give 22S-5, and an activation relay process for selective breakage of C16O bond in furostanol to deliver 22R-17.
