英文摘要	multisubstituted pyrazoles were efficiently synthesized by cyclocondensation of beta-thioalkyl-alpha,beta-unsaturated ketones with hydrazines under relatively mild conditions. a one-pot synthetic protocol through tandem liebeskind-srogl cross-coupling/cyclocondensation using alpha-oxo ketene dithioacetals as the starting materials was also realized for the same purpose.
