The first total synthesis of (-)-spirangien A, a cytotoxic and antifungal polyketide of myxobacterial origin, is reported; this exploits a Stork-Wittig olefination and double Stille cross-coupling sequence to install the sensitive pentaene side chain onto a fullyelaborated spiroacetal core, leading initially to the methyl ester of spirangien A.
