demonstrated by the synthesis of an intermediate of a bioactive compound on a large scale. A facile and widely applicable method for the synthesis of N-substituted amidesfrom alkenes and amides using Brønsted acids was developed. Treatment of various alkenes with amides and an alkali metal halide or methanesulfonic acid in trifluoroacetic acid afforded the corresponding N-substituted amides in good to high
