The syntheses of three diacetylenic isobutylamides of Echinacea angustifolia have been achieved by direct synthetic routes by way of a common intermediate. The key step is the alkylation of the anion of the silylated diacetylene. We report the presence of all three diacetylenic isobutylamides in six of the nine Echinacea species: E. angustifolia, E. sanguinea, E. simulata, E. tennesseensis, E. ...
