Other Methods for Carbocyclic Construction: 6,11-Epoxyisodaucane (Tanino), Magellanine (Yao), Nemorosonol (Ohyoshi/Kigoshi), Antroalbocin (Kalesse), Cochlearol B (Schindler), Emerione A (Miller)
6,11-Epoxyisodaucane (3) was isolated from the liverwort Tritomaria polita. In the course of the synthesis of 3, a key step of which was the decyanative cyclization of the epoxide 1…
