Total Synthesis of (+/-)-Sesbanimide A and B

The total synthesis of sesbanimide A (1) and B (2) is reported which features (a) the reaction of cyclopentadiene with glyoxylic acid leading to the useful bicyclic lactone building block 3 and (b) the use of 2.5 mol/ dm-3 lithium perchlorate i

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.

A Total Synthesis of (-)-Sesbanimide A

The molecule (-)-sesbanimide A (1), the optical antipode of the potent cytotoxic natural product (+)-sesbanimide A (2), has been prepared starting from the aldehyde 3 via a brief and efficient reaction pathway.
