ethyl pyrrole-2-carboxylate (4) via a new synthetic route, the following chemical correlation work was performed. Ethyl 9-methoxybenz[f]in-dole (8a) was converted to 1-benzyl-3-methyl-5,6,7,8-tetrahydrobenz[f]indole (25), which was alternatively and authentically synthesized from ethyl 3-methylpyrrole-2-carboxylate (11). On the basis of the established route to the benz[f]indole nucleus, two representative
为了确认由吡咯-2-羧酸乙酯(4)通过新的合成路线制备的乙基9-甲氧基苯并[ f ]吲哚(8a)的结构,进行了以下化学相关工作。乙基-9- methoxybenz [ ˚F ]吲哚(8A)转化为1-苄基-3-甲基-5,6,7,8-四氢苯并[ ˚F ]吲哚(25),其被交替和真实从3-合成-甲基吡咯-2-羧酸酯(11)。根据到苯并[ f ]吲哚核的确定路线,两个代表性苯并[ f ]吲哚,苯并[ f ]吲哚(1)和4,9-dioxobenz [ f ]吲哚(26)。
