dissociates to the quinone 1 and quinone methide 2 which recombine with elimination of p-methoxybenzyl alcohol to form the xanthylium salt 9a. With zinc and acetic acid 3 yields isormeric meso- and dl-ethylenediquinol derivatives 14a. Sodium borohydride reduction of 3 yields an alcoholic quinol 5a which rapidly reoxidizes to the spiro-tetrahydrofuran derivative 24a. Possible mechanisms which may be involved
在强酸溶液中,二聚体3解离为醌1和醌甲基化物2,它们在消除对甲氧基苄醇的情况下重新结合,从而形成x盐9a。用锌和乙酸3产生异构体的内消旋内消旋和内消旋的亚乙基二喹啉衍生物14a。硼氢化钠还原为3会生成醇喹诺醇5a,该醇喹诺醇5a迅速重新氧化为螺四氢呋喃衍生物24a。讨论了可能与这些重排产物的形成有关的机制。
