A strategy for the synthesis of spirocarbocycles by using chloromethyl arenes as starting materials is described in this paper. The palladium-catalyzed allylative dearomatization and the subsequent ruthenium-catalyzed ring closure metathesis proceeded smoothly under mild conditions to produce the corresponding spirocarbocycle products with moderate to high yields. Benzene-ring-, naphthalene-ring-,
本文介绍了一种以氯甲基芳烃为起始原料合成螺碳环的策略。钯催化的烯丙基脱芳构化和随后的钌催化的闭环复分解在温和条件下顺利进行,以中等至高产率生产相应的螺碳环产物。通过使用所提出的方法,含苯环、萘环和蒽环的底物可以很容易地转化为螺碳环。
