The first total syntheses of (+)-alismoxide and (+)-4-epi-alismoxide are reported. Formal chemo-, regio-, and stereoselective addition of water to 10α-acetoxy-1αH,5βH-guaia-3,6-diene afforded the target compounds after reduction. The absolute stereochemistry of (+)-alismoxide has been established. The low [α]D +8.6 value indicates that significant amounts of alismoxide result from biosynthetic processes
