β¦ Synopsis
Two alternative synthetic routes of the left-half segment 5 have been developed. Efficient condensation between the left and right segments followed by Pd-catalyzed deoxygenation and further elaboration achieved the first total synthesis of AAL-toxin TAI. This allowed us to synthesize various AAL-toxin analogs which would be useful for investigating SAR studies of AAL-toxins.

## Abetract Three segments A, B and C for okadaic acid synthesis were coupled with each other in the order of At(BtC), the key steps of the twice couplings being between sulfone carbanions and aldehydea. After the BtC coupling, the asymmetric center C-27 was generated by a hydride reduction of the
