Design, synthesis and insecticidal activities of 4-propargyloxybenzene sulfonamide derivatives substituted with amino acids.

Sixty-nine 4-propargyloxybenzene sulfonamide derivatives with different amino acids as amino substituent were synthesized and evaluated for their insecticidal activity against third-instar . The bioassay results revealed that some derivatives bearing amino acid ester group performed good insecticidal activity against third-instar , such as the LC values of and were 4.28 and 2.
