Abstract

New dimers, (±)-bisdehydroanonaine 5a, (±)-bisdehydroxylopine 5c, (±)-bisdehydronornantenine 5d and (±)-7-dehydroxyiopinyl-7’-dehydronornantenine 8, and the previously described (±)-urabaine 5b, were prepared from dehydroxyiopine 3c and known dehydronoraporphines 3a, 3b, and 3d via dimerization at the β-carbon of cyclic secondary enamines.
