Abstract

A highly efficient Pt-catalyzed [3,3] sigmatropic rearrangement/cyclization cascade of <i>N</i>-propargylhydrazones is reported. The process provides expedient access to a variety of highly functionalized pyrazoles. The substrate has good substituted group compatibility, and the bioactive 3-CF<sub>3</sub> pyrazoles could be synthesized easily with this method
