A new and efficient synthesis of a naturally occurring amide alkaloid, N-isobutyl-4,5-epoxy-2(E)-decenamide isolated from the roots of Piper nigrum has been described involving a total of nine steps. Octanal and 2-bromoacetic acid have been used as the starting materials.
Abstract The structure, N-isobutyl-4,5-dihydroxy-2(E)-decenamide, for sylvamide is confirmed by its totalsynthesis. The erythro stereochemistry is also established by comparison of the properties of the natural and synthetic samples.
