摘要：
New type of substituted 1H-pyrazole-4-carboxamides were obtained by regioselective synthesis under the catalysis of different bases. The structures of the title compounds were confirmed by elemental analysis, 1H NMR, IR, MS and X-ray crystallography. Compounds 1 were transacylated into their corresponding amides 3 in the presence of sodium hydride. Preliminary bioassays indicated that some compounds showed fungicidal activities against Rhizoctonia solani and Sclerotinia sclerotiorum.
