Reactions of N- and C-alkenylanilines: X. Synthesis of 2-vinyldihydroindoles from 4-methyl-2-(pent-3-en-2-yl)aniline
摘要:
2-(1-Iodoethyl)-3,5-dimethyl-1-(4-methylphenylsulfonyl)-2,3-dihydro-1H-indole reacted with pyridine, piperidine, N-alkylpiperidines, and dimethylformamide to give dehydrohalogenation and halogen substitution products whose ratio depended on the reagent structure. Heating of 2-(1-iodoethyl)-3,5-dimethyl-1-methylsulfonyl-2,3-dihydro-1H-indole with piperidine resulted in the formation of only dehydroiodination products.
