The short-step synthesis of the unsubstituted, 5-hydroxy- and 5-chloropiperidazine-3-carboxylic acids using an aza Diels-Alder reaction between the 1,3-diene and azodicarboxylate was described. This synthetic methodology could be used for the preparation of the optically active piperazic acid in a 35% overall yield.
描述了使用1,3-二烯和偶氮二羧酸酯之间的氮杂Diels-Alder反应进行未取代的5-羟基和5-氯哌嗪-3-羧酸的短程合成。该合成方法可用于以35%的总产率制备旋光性哌嗪酸。
