Abstract The hydantoin moiety has proved to be an important pharmacophore that confers a wide range of biological properties to different derivatives. Thus, synthetic methods have been developed to obtain such molecules. Herein, we describe the heterocyclization process to obtain imidazolidine-2,4-diones (hydantoin compounds) from methylcyclobutyl ketones and cyclobutanones derived from (−)-(1S)-α-pinene
摘要 乙内酰脲部分已被证明是一种重要的药效团,赋予不同衍生物广泛的生物学特性。因此,已经开发了合成方法来获得这样的分子。在此,我们描述了从甲基环丁基酮和衍生自 (-)-(1S)-α-蒎烯和 (-)-(1S)-verbenone 的环丁酮中获得咪唑烷-2,4-二酮(乙内酰脲化合物)的杂环化过程。 Bucherer-Berg 反应。得到的甲基环丁基乙内酰脲和螺乙内酰脲被充分表征,通过核磁共振实验和理论计算确定了它们的绝对立体化学。
