The novel trans-bicyclic-perhydro-2(1H)-quinoxalinones 4, 6 and 7 and the tricyclic-perhydropyrrolo[1,2-a]-quinoxalin-4(5H)-one derivatives 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
新颖的反式-二环-全氢化2(1 ħ)-quinoxalinones 4,6和7和三环-全氢[1,2一]喹喔啉-4(5 ħ) -酮衍生物8和9制备经由一个氮丙啶2和3与α-氨基酸甘氨酸,L-丙氨酸,L-脯氨酸和L-苯丙氨酸的开环和自发的闭环反应。该方法用于制备5和10,它们是κ阿片类化合物1的新型刚性类似物。氮丙啶3的处理用氨基甲酸甲酯得到环状脲11。
