The aza-Claisen rearrangement of vinylpyrrolidines 1 yielded almost exclusively the trans-3,8-disubstituted nine-membered ring lactams 2 (TBS=tBuMe Si), independent of whether cis or trans isomers were used as starting materials. The conformation (which provided facial chirality) of the medium-sized

Starting from condensation of two iridoid synthons, (3S,8R)-benzyloxy-l-iriden-7-al and (3R)-7-chloro-l-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
