From the corresponding heterocyclic amino acids 2 and 9a the heterocyclic systems imidazo[1,5-a]pyridine (3) and imidazo[1,5-a]quinoline (10) are easily accessible. From compound 7 the tricyclic system 11 was prepared and from compound 17a a pyridyl-1,2,4-triazinone (18) could be obtained.
从相应的杂环氨基酸2和9a,可容易地获得咪唑并[1,5- a ]吡啶(3)和咪唑并[1,5- a ]喹啉(10)的杂环系统。由化合物7制备三环系统11,并由化合物17a获得吡啶基-1,2,4-丁三嗪酮(18)。
