towards the structurally complex and highly decorated framework of B-seco limonoid natural products by means of a [3,3]-sigmatropic rearrangement are described. Detailed model studies reveal, that an Ireland-Claisen rearrangement can be employed to construct the central C9-C10 bond thereby giving access to the B-seco limonoid scaffold. However, application of the developed strategy ended up failing
描述了通过 [3,3]-sigmatropic 重排对 B-seco 柠檬苦素类天然产物的结构复杂和高度装饰框架的合成研究。详细的模型研究表明,可以采用爱尔兰-克莱森重排来构建中央 C9-C10 键,从而获得 B-seco 柠檬苦素支架。然而,开发策略的应用最终在更复杂和空间要求更高的系统中失败。
