As an important building block, developing efficient and green synthesis strategy of cyclohex-2-enones is of great importance. In this present work, a general approach to the mild synthesis of substituted cyclohex-2-enones derivatives starting fro m simple aldehydes and acetone have been achieved via d-aminoacylase-initiated Aldol condensation/Robinson annulation cascade reaction using imidazole as
作为重要的组成部分,开发高效且绿色的环己-2-烯酮合成策略非常重要。在本工作中,已通过使用咪唑作为有机添加剂的d-氨酰基酶引发的Aldol缩合/鲁宾逊环化级联反应,实现了由简单的醛和丙酮轻度合成取代的环己-2-烯酮衍生物的一般方法。媒体。系统地研究了反应条件对溶剂,酶浓度,添加剂类型,酶与添加剂的摩尔比,底物范围等的影响。此外,设计了一些实验来探索d的催化作用。-氨基酰化酶和咪唑在多步级联过程中,并提出了一种可能的机理。
