    Synthesis of 4(5)-[5-(Aminomethyl)tetrahydrofuran-2-yl- or 5-(Aminomethyl)-2,5-dihydrofuran-2-yl]imidazoles by Efficient Use of a PhSe Group:  Application to Novel Histamine H3-Ligands1
    摘要:
    将以下文本翻译成中文: (+)-4(5)-[(2R,5S)-(5-Aminomethyl)tetrahydrofuran-2-yl]imidazole 1 and its C2' epimer (-)-2, which are the 5'-amino derivatives of a novel imidazole C-nucleoside, were synthesized via beta- and alpha-2'-phenylselenenyl nucleosides 15 and 16. The anomers 15 and 16 were provided by a new synthetic method for C-nucleosides via the elimination of PhSeCl and selenocyclization from diol intermediates 12 and 14, starting from L-glutamic acid. Their ent-1 and ent-2 (imifuramine), the latter of which was indicated as a novel type of histamine H-3-agonist confirmed by an in vivo brain microdialysis method, were synthesized by the same methodology from D-glutamic acid. The four isomers (3, 4, ent-3, and ent-4) of a 4(5)-[(5-aminomethyl)-2,5-dihydrofuran-2-yl]imidazole were also synthesized via the oxidative elimination of the PhSe group of the key intermediates (15, 16, ent-15, and ent-16). In connection with this study, 4(5)-(5-aminomethylfuran-2-yl)-1H-imidazole (5) was also synthesized starting from D-ribose. --- (+)-4(5)-[(2R,5S)-(5-氨基甲基)四氢糠基-2-基]咪唑 1 与其 C2' 异构体 (-)-2,作为新型咪唑 C-核苷的 5'-氨基衍生物,通过 beta- 和 alpha-2'-苯基硒基核苷 15 和 16 合成。15 和 16 这种异构体通过一种新型 C-核苷合成方法制得,从 L-谷氨酸出发,通过二醇中间体 12 和 14 消除 PhSeCl 并进行硒环化反应。其 ent-1 和 ent-2(咪吗啡啉),其中后者被确认为一种新型组胺 H-3 �受体激动剂,通过体内脑微透析方法验证,也由此从 D-谷氨酸制得。此外,通过关键中间体(15、16、ent-15 和 ent-16)中 PhSe 基团的氧化消除,合成了 4(5)-[(5-氨基甲基)-2,5-二氢糠基-2-基]咪唑的四种异构体(3、4、ent-3 和 ent-4)。与本研究相关,4(5)-(5-氨基甲基糠基-2-基)-1H-咪唑 (5) 也从 D-核糖开始制得。
