  Total synthesis of optically active cotylenol, a fungal metabolite having a leaf growth activity. Intramolecular ene reaction for an eight-membered ring formation

  摘要：

  Starting from condensation of two iridoid synthons, (3S,8R)-benzyloxy-1-iriden-7-al and (3R)-7-chloro-1-iridene, cotylenol, one of the representative fusicoccane diterpenoids having 5-8-5-membered tricyclic carbon framework, is now synthesized for the first time via an eight-membered ring formation by an intramolecular ene reaction and subsequent introduction of an alpha-hydroxyl group.
