involving as featuring steps a transition metal catalyzed atom transfer radical cyclization and a functional rearrangement of the polyhalogenated 2-pyrrolidinones thus obtained, are described. Both routes use 10-undecenoic acid, a renewable source from castor oil, as starting material for the preparation of the pivotal intermediates α,α,α′,α′-tetrachlorodicarboxylic acids.
描述了酪霉素A和非天然低级同系物的合成,其特征在于包括过渡金属催化的原子转移自由基环化和由此获得的多卤代2-吡咯烷酮的功能性重排。两种路线均使用10-十一碳烯酸(一种蓖麻油的可再生资源)作为制备关键中间体α,α,α',α'-四氯二羧酸的原料。
