idine (40). Condensation of 27, 35, and 40 with diethyl or di-tert-butyl L-glutamate followed by removal of the ester groups yielded N-[4-[3-(2,4-diamino-6(5H)-oxopyrimidin-5-yl)pyr-rolidino]benzoyl]-L-glutamic acid (13), N-[4-[4-(2,4-diamino-6-(5H)-oxopyrimidin-5-yl)piperidino]benzoyl]-L-glutamic acid (14), and N-[4-[3-(2,4,6-triaminopyrimidin-5-yl)pyrrolidino]benzoyl]-L-glutamic acid (15). Compounds
将1- [4-(叔丁氧基羰基羰基)苯基] -3-吡咯烷酮和1- [3-(叔丁氧基羰基)苯基] -4-哌啶酮与氰基乙酸乙酯或丙二腈缩合以形成亚烷基衍生物,然后依次对其进行处理。 (i)催化或化学还原,(ii)与胍缩合,和(iii)温和三氟乙酸处理以获得3-(2,4-二氨基-6(5 H)-氧嘧啶丁-5-基)- 1-(4-羧基苯基)吡咯烷(27),4-(2,4-二氨基-6(5 H)-氧嘧啶丁-5-基)-1-(羧基苯基)哌啶(35)和3-(2, 4,6-三氨基嘧啶-5-基)-1-(羧苯基)吡咯烷(40)。的缩合27,35,和40用二乙基或L-谷氨酸二叔丁基酯,然后除去酯基,得到N- [4- [3-(2,4-二氨基-6(5H)-氧嘧啶丁-5-基] pyr-rolidino]苯甲酰基] -L-谷氨酸(13),N- [4- [4-(2,4-二氨基-6-(5 H)-氧嘧啶丁-5-基)哌啶子基]苯甲酰基] -L-谷氨酸(14),和N-
