A non-chiral, rigid 7-azabicyclo[2.2.1]heptane-1,4-dicarboxylic acid, an analogue of 2-aminoadipic acid, has been synthesized in six steps from dimethyl-meso-2,5-dibromohexanedioate in 28% total yield. A key step in the synthesis is double alkylation of a dimethyl pyrrolidine-2,5-dicarboxylate by 1-bromo-2-chloroethane.
非手性的,刚性的7-氮杂双环[2.2.1]庚烷-1,4-二羧酸,是2-氨基己二酸的类似物,是由28%的二甲基-内消旋-2,5-二溴己二酸二甲酯合成的。总产量。合成中的关键步骤是吡咯烷2,5-二羧酸二甲酯被1-溴-2-氯乙烷双重烷基化。
