investigated. Convenient syntheses of dihydropleiadene and some of its derivatives are described. The stereochemistry of the dimers and N-phenylmaleimide adducts of pleiadene, acepleiadene and acepleiadylene have been determined by a detailed NMR study; all of the dimers have the anti configuration, while the adducts all have the exo configuration.
