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.
