A regio-selective and consecutive Michael-Claisen process has been developed for substituted cyclohexane-1,3-dione synthesis started from unsubstituted or substituted acetone and α,β-unsaturated esters. Substituted cyclohexane-1,3-diones are the basic unit found in several natural products, bioactive alkaloids and acridine dione type heterocycles, polyphenols, and unnatural amino acid synthesis. Most of the potent herbicidal and pesticidal active molecules contain cyclohexane-1,3-dione derivatives. Such an important intermediate synthesis using a facile, atom economy and one-pot process is a demandable area in organic synthesis.
已开发出一种用于合成取代环己烷-1,3-二酮的区域选择性和连续的Michael-Claisen过程,该过程始于未取代或取代的丙酮和α,β-不饱和酯。取代环己烷-1,3-二酮是几种天然产物、生物活性生物碱和吖啶二酮类杂环、多酚以及非天然氨基酸合成中发现的基本单元。大多数有效的除草剂和杀虫剂活性分子含有环己烷-1,3-二酮衍生物。利用简便、原子经济和一锅法过程进行如此重要的中间体合成是有需求的有机合成领域。
