Condensation reactions of a nitrodienamine (1) with Grignard and organocopper reagents prepared from indole derivatives were investigated. Indolyl Grignard reagents were prepared from 4-bromoindole (3a), 5-bromoindole (3b), 6-bromoindole (3c), and 5-nitroindole (3d) using methylmagnesium bromide. Indolyl organocopper reagents were prepared from indole (3e), 2-methylindole (3f), and 3-methylindole (3g) using dimethylcopperlithium.
