Adamantane and cyclooctane lipophilic 2,6-diketopiperazines (2,6-DKPs) have been prepared by a simple and effective method, including the synthesis of the corresponding iminodiacetic amido-ester derivatives and their intramolecular cyclization. In this method, the key step of the imide formation was accomplished by a novel base-induced cyclization protocol, which involved the treatment of amido-ester
已通过简单有效的方法制备了金刚烷和环辛烷亲脂性2,6-二酮哌嗪(2,6-DKPs),包括合成相应的亚氨基二乙酸酰胺基酯衍生物及其分子内环化作用。在这种方法中,酰亚胺形成的关键步骤是通过新型的碱诱导的环化方案完成的,该方案包括用双(三甲基甲硅烷基)酰胺钾处理酰胺基酯2,6-DKP前体。此外,使用相同的环化方法,可以在一个锅中合成各自的1-官能化的2,6-DKP,并且当相同的伯酰胺酯用先前的碱处理,然后使中间体亚氨酸钾盐与之反应时,即可以极高的产率合成相应的1-官能化的2,6-DKP。亲电子溴乙酸苄酯。苄基2的氢解
