A stereoselective route for the totalsynthesis of anticancer marine natural product (+)-varitriol (1) is detailed herein. The impressive biological activity and interesting structural features of natural (+)-varitriol fuelled us to undertake the synthesis of some higher analogues (1a–j) of this molecule. The key features of the synthetic strategy include one-pot Wittig olefination followed by a highly
