参考标题:A General And Regioselective Synthesis Of 5-Trifluoromethyl-Pyrazoles 作者:Robert S. Foster,Harald Jakobi,Joseph P. A. Harrity |发布日期:2012.9.21 摘要:Two Synthetic Approaches To 4-Trifluoromethylsydnones, A Novel Class Of These Mesoionic Reagents, Are Reported. These Compounds Undergo Regioselective Alkyne Cycloaddition Reactions, Thereby Providing A General Approach To 5-Trifluoromethylpyrazoles. This Method Has Been Employed In A Short Formal Synthesis Of The Herbicide Fluazolate.
