(S)-(+)-4,4,4-Trifluoro-3-(indole-3-)butyric acid, a novel fluorinated plant growth regulator

Racemic 4,4,4-trifluoro-3-(indole-3-)butyric acid (TFIBA) has been synthesized and shown to inhibit oat coleoptile elongation. (S)-(+)-TFIBA, which was prepared by an enzymatic method, promoted root growth of Chinese cabbage, lettuce and rice plants.
