New variation in the Nazarov cyclization has been developed by preparing divinyl and arylvinyl epoxides as pentadienyl cation precursors for the first time. Highly substituted cyclopentadienes, hydrindienes, and indenes were synthesized to demonstrate the compatibility of this reaction with substrates bearing a variety of substitutions and having different types of epoxides. Application of this method
通过首次将二乙烯基和芳基乙烯基环氧化物制备为戊二烯基阳离子前体,已开发出Nazarov环化的新变化形式。合成了高度取代的环戊二烯,羟基和茚基,以证明该反应与带有各种取代基和环氧化物类型不同的底物的相容性。还证明了该方法在合成以白藜芦醇为基础的天然产物中的应用。
