Stereoselective total synthesis of natural (+)-streptazolin via a palladium-catalyzed enyne bicyclization approach

The natural Z isomer of (+)-streptazolin (1), isolated from cultures of Streptomyces viridochromogenes, was synthesized in an optically pure form for the first time on the basis of a palladium-catalyzed enyne bicyclization approach in 12 steps and 4.3% ov
