Аннотация:Cyanoalkylation of indoles and pyrroles using 4,4,4-trifluoro-2-butenonitrile in the presence of aluminium bromide was used to synthesize 4,4,4-trifluoro-substituted 3-(indol-3-yl)- and 3-(pyrrol-2-yl)butanonitrites, which are converted by saponification of the nitrile group into 3 heteroaryl-substituted 4,4,4-trifluorobutyric acids.
