Suzuki 交叉偶联反应中溴吡咯酯的甲酰基活化:应用于 Polycitone A 和 B 以及 Polycitrin A 的正式合成
摘要:
描述了一种新的吡咯构件,它允许 2,3,5-三取代的吡咯和 2,3,4,5-四取代的吡咯的区域特异性合成。介绍了制备吡咯结构单元的优化研究以及对各种交叉偶联条件和交叉偶联剂的评估。还描述了从吡咯构建块合成天然产物 Polycitone A、Polycitone B 和 Polycitrin A 的简短正式合成。

Lycogarubin C, permethyl storniamide A, and lamellarinGtrimethylether are pyrrole containing, natural products, which exhibit interesting biological properties. Such properties include anti-tumor activity on a variety of cancer cell lines including those that confer drug resistance, inhibition of HIV integrase, and vascular disrupting activity. We now describe the use of methyl and ethyl 3-brom

New microtubule depolymerizing agents with potent cytotoxic activities have been prepared with a 5-cyano or 5-oximino group attached to a pyrrole core. The utilization of ortho activation of a bromopyrrole ester to facilitate successful Suzuki-Miyaura cross-coupling reactions was a key aspect of the synthetic methodology. This strategy allows for control of regiochemistry with the attachment of four
