The Diels-Alder adduct 5 derived from the N-butynylmaleimide 6 and cyclopentadiene has been transformed into the tetracyclic lactams 12 and 19 via a common precursor 9.The lactams 12 and 19 have been converted into (+)-indolizidine 1 and (+)-laburnine 2, respectively, via retro-Diels-Alder reaction.Similar methodology has bee succesfully applied to the synthesis of (+)-elaeokanine A 3 and (+)-elaeokanine C 4.
