| Research Abstract |
A total synthesis of (-)-polycavernoside A, a marine lethal toxin isolated from the edible alga Gracilaria edulis, has been achieved via a convergent approach. The synthesis is highlighted by catalytic asymmetric syntheses of the two key fragments and their union through Suzuki-Miyaura coupling and Keck macrolactonization. Efficient synthesis of L-fucosyl-D-xylose part was developed by using armed-disarmed concept.
