Résumé

2-Methylindole-3-acetic acid (2-Me-IAA) is a known auxin, but its 2-ethyl homologue has been considered inactive. Here we show that the compound previously bioassayed as '2-ethylindole-3-acetic acid' (2-Et-IAA) was, in fact, 3-(3-methylindol-2-yl)propionic acid. The proper 2-Et-IAA and its 2-(n-propyl) homologue (2-Pr-IAA) are prepared, unambiguously characterized, and their auxin activity is demonstrated in the Avena coleoptile-section straight-growth test. Their half-optimal concentrations are approximately the same as for 2-Me-IAA ...
