The Diels-Alderreactions between vinylindenes (5 or 6) as the dienes with quinoneketals (7 or 8) or with methacrolein as the dienophiles were investigated. The remarkable regioselectivities of these Diels-Alder adducts suggested that the regiopreferences of these dienes and dienophiles in these cases are not a fixed property of each component of the cycloaddition but are mutually contigent.

研究了作为二烯的乙烯基茚(5 或 6)与醌缩酮(7 或 8)或甲基丙烯醛作为亲二烯体之间的 Diels-Alder 反应。这些 Diels-Alder 加合物的显着区域选择性表明,在这些情况下,这些二烯和亲二烯体的区域偏好不是环加成的每个组分的固定特性,而是相互并存的。本文展示了如何将 6 和 8 之间的 Diels-Alder 反应应用于氟他汀 C 和 E 的首次全合成。
