enantiospecific total synthesis of rhodexin A via a very hindered inverse electron demand Diels–Alder reaction are described. The C8-diastereomer of the fully elaborated tetracyclic core of rhodexin A, 23, was prepared in good yield and excellent selectivity using as the key step the stepwise Diels–Alder reaction of the very hindered dienone 3 and the silyl enol ether 4 catalyzed by the very strong Lewis
描述了通过非常受阻的逆电子需量Diels-Alder反应对罗德毒素A的对映体全合成的研究。的C8-非对映体的完全阐述rhodexin A,的四环核心23,使用作为关键步骤的逐步的非常Diels-Alder反应的受阻二烯酮以良好的收率和良好的选择性制备3和甲硅烷基烯醇醚4催化由很强的路易斯酸,三氟甲基二甲基铝。
