4,4-trifluoro-3-(indole-3-)butyric acids (TFIBAs), novel fluorinated plant growth regulators, were easily synthesized from substituted 2,2,2-trifluoro-l-(indole-3-)ethanols. The synthetic substituted TFIBAs showed marked root growth-promoting activity toward Chinese cabbage, lettuce, and rice plants. 5-MeO-2-Me-TFIBA (2d) had especially strong promoting activity toward Chinese cabbage, while 5-Me-
取代的2,2,2-三氟-1-(吲哚-3-)可以轻松合成取代的4,4,4-三氟-3-(吲哚-3-)丁酸(TFIBA),这是一种新型的氟化植物生长调节剂。乙醇。合成的取代的TFIBA对大白菜,生菜和水稻植株显示出明显的促进根系生长的活性。5-MeO-2-Me-TFIBA(2d)对大白菜具有特别强的促进活性,而5-Me-TFIBA(2b)显着促进了所有三种植物的根部生长。在分子的吲哚核(5-Br-和5-C1-TFIBA(2e和2g))的5-位卤化的TFIBA的促进活性也大于原始的非取代化合物TFIBA的活性。具有强吸电子基团的5-N02-TFIBA(2h)仅表现出非常弱的促根生长活性。
