A new derivative of fipronil: Effect of adding a glycinyl group to the 5-amine of pyrazole on phloem mobility and insecticidal activity

Glycinyl fipronil, a new fipronil derivative with 5-amine acylated by glycine, was synthesized. The phloem mobility of the synthesized derivative was higher that of the parent compound in intact soybean seedling and its insecticidal activity against the 3rd instar larvae of Plutella xylostella was comparable with that of fipronil.
