The first convergent total synthesis of isobongkrekic acid is reported involving three different stereospecific palladium cross-couplings for the formation of the diene units. Access to bongkrekic acid by this route is also demonstrated. These syntheses involve the formation of several potentially general building blocks.

An efficient totalsynthesis of (+)-bongkrekic acid, a potent apoptosis inhibitor, has been accomplished by employing a convergent strategy based on the Suzuki-Miyaura coupling of three fully functionalized segments. apoptosis - conjugated diene - Suzuki-Miyaura coupling - palladium - bongkrekicacid

An efficient total synthesis of the apoptosis inhibitor bongkrekic acid was accomplished using a three-component convergentstrategy involving a Kocienski-Julia olefination and a Suzuki–Miyaura coupling, in which the longest linear sequence was 18 steps and proceeded in 6.4% overall yield. The torquoselective olefination also contributed to the shortening of the synthesis.
