摘要
A series of novel pyrazole carboxamides were designed and synthesized through multi-step reactions from ethyl acetoacetate and triethyl orthoformate, and their structures were characterized by Fourier transform infrared, H-1-NMR, C-13-NMR, mass spectrometry, and elemental analysis. The preliminary insecticidal activity showed that some of them possessed good insecticidal activities against Meloidogyne incognita.
