The total syntheses of pusilatins A (2), B (3), and C (5), macrocyclic bisbibenzyl dimers isolated from Japanese liverwort are reported. The common monomeric unit (6) was prepared via macrocyclization of an o-sulfinylfluorobenzene derivative by SNAr attack of an internal phenol, which was exploited for site-selective dimerizations en route to 2, 3, and 5.
据报道,总葛素素A(2),B(3)和C(5),大环双联苄二聚体从日本地蒿中分离得到。共用单体单元(6)通过的大环化制备的ö -sulfinylfluorobenzene由S衍生物Ñ内部苯酚,将其开发用于位点选择性dimerizations途中的攻击的Ar 2,3,和5。
