The firsttotalsynthesis of (−)-bitungolide B and a second-generation totalsynthesis of (−)-bitungolide E are described. The cornerstone of the approach comprises a convergent and flexible route involving Brown crotylation, highly diastereoselective substrate controlled Paterson anti-aldol reaction, hydroxyl-directed 1,3-syn/anti reduction, Barton–McCombie deoxygenation and RCM reactions. Via this
