The novel trans-bicyclic-perhydro-2(1H)-quinoxalinones 4, 6 and 7 and the tricyclic-perhydropyrrolo[1,2-a]-quinoxalin-4(5H)-onederivatives 8 and 9 are prepared via a ring opening and spontaneous ring closing reaction of the aziridines 2 and 3 with the α-amino acids glycine, L-alanine, L-proline and L-phenylalanine. This methodology was used to prepare 5 and 10 which are novel rigid analogues of the
