本文描述了含海英酮的海绵代谢物乙酰海英酮的短合成。该合成的一个关键特征是假定的仿生,α功能化咪唑酮5的分子内环化,它提供了包含6的三环吡咯氮平酮框架。此外,本文还概述了咪唑酮类化合物转化为α、β -不饱和邻苯二甲酸酯类化合物的新方法。
A short synthesis of the hydantoin-containing marine sponge metabolites axinohydantoins is described. A key feature of the synthesis is a putative biomimetic, intramolecular cyclization of alpha-functionalized imidazolone 5, which affords the tricyclic pyrroloazepinone framework comprising 6. In addition, the conversion of imidazolones to alpha,beta-unsaturated hydantoins is outlined and represents a new approach to these heterocyclic systems.
