摘要

The palladium (0)-catalyzed carbonylations, in acetic acid as a necessary solvent, of 2, 7- octadienyl acetate and homologues via π-allylpalladium species were preceded by their intramolecular olefin insertion to form mixtures of cis/trans-2-vinylcyclopentylacetyl-and cis/trans-cyclohexylacetylpalladium intermediates, which undergo further the intramolecular (5-exo) Heck reaction to give bicyclo-[3.3. 0] and [4.3. 0] skeletons, respectively, except for ...
