The totalsynthesis of the title compound (1), starting with (R)-(−)-α-phellandrene (6), has been accomplished. The synthesis rigorously proves the relative stereochemical relationship of the diterpenoid and carbohydrate domains of eleutherobin. Key reactions included a Nozaki−Kishi ring closure to produce a furanophane (see 37 → 38), a pyranose to furanose transposition (see 50 → 47), and a novel
