EFFICIENT SYNTHESIS AND ANTITUMOR ACTIVITY OF AN ENANTIOMERIC PAIR OF THE SESBANIMIDE AB-RING SYSTEMS

An enantiomeric pair of the fully unprotected AB-ring systems of sesbanimide A (1), a potent antitumor alkaloid, was efficiently synthesized from readily available D- and L-xylose.Examination on their in vitro antitumor activity clearly disclosed that the AB-ring system only made a small contribution to the notable cytotoxicity of 1.

An alternative synthesis of (+)-sesbanimide A

D-(+)-xylose has been converted to (+)-sesbanimide A in sixteen steps.The synthetic scheme involves an ususual tricyclic silylated derivative (9a) of the monobenzoylated product of the earlier described glutarimide intermediate (7).Compound 9a is a pivotal intermediate for the construction of ring C of (+)-sesbanimide A.
