A new, conformationally rigid analogue of 2-aminoadipic acid, 8-[(benzyloxy)carbonyl]-3-methylene-8-azabicyclo[3.2.1]octane-1,5-dicarboxylic acid, is synthesized from dimethyl rac-2,5-dibromohexanedioate. The key steps involve alkylation-cyclization of 1-benzyl 2,5-dimethyl pyrrolidine-1,2,5-tricarboxylate with 3-chloro-2-(chloromethyl)prop-1-ene to yield the 8-azabicyclo[3.2.1]octane skeleton.
一种新型构象刚性的2-氨基己二酸类似物,即8-[(苄氧基)羰基]-3-亚甲基-8-氮杂双环[3.2.1]辛烷-1,5-二羧酸,由外消旋二甲基2,5-二溴己二酸酯合成。关键步骤包括1-苄基2,5-二甲基吡咯烷-1,2,5-三羧酸酯与3-氯-2-(氯甲基)丙-1-烯的烷基化-环化反应,生成8-氮杂双环[3.2.1]辛烷骨架。
