Regioselective electrophilic aromatic substitutions, acylation, bromination, and formylation, of unprotected pyrido[2,3- B]indole (α-carbolines) at the C-6 position are described. Alter-native conditions for the nitration were investigated, which led to the -unexpected appearance of the minor C-8 isomer.
描述了未受保护的吡啶并 [2,3-B] 吲哚(α-咔啉)在 C-6 位置的区域选择性亲电芳香取代、酰化、溴化和甲酰化。研究了用于硝化的替代条件,这导致了次要 C-8 异构体的意外出现。
