aminomethylation of pyrrole and indole with N,N,N′,N′-tetramethylmethanediamine in the presence of 5 mol % of ZrOCl2·8H2O proceeds selectively at the positions 2, 5 of pyrrole and 1, 3 of indole. Carbazole under the same conditions affords 3-formyl-9-aminomethyl derivative. The reaction in the presence of 5 mol % of K2CO3 occurs as monoaminomethylation: for pyrrole at the position 2, for indole at the position
吡咯和吲哚与催化氨基甲基Ñ,Ñ,N' ,N'在5摩尔%的ZrOCl的存在-tetramethylmethanediamine 2 ·8H 2 ö选择性地在位置前进2,5吡咯和1,3吲哚。在相同条件下,咔唑得到3-甲酰基-9-氨基甲基衍生物。在存在5 mol%K 2 CO 3的情况下,该反应以单氨基甲基化形式发生:对于位置2的吡咯,对于位置3的吲哚,以及在底物氮原子上的咔唑。水溶性1,1'-(1 H-吡咯-2,5-二基)双(N,N-二甲基甲胺)对植物致病性真菌Rhizoctonia solani具有抑菌活性。
