Fused polycyclic pyrazoles are an important type of heterocyclic compounds, thus, the development of efficient methods for their preparation becomes highly urgent. Herein, we reported an efficient method for the...

An efficient Cu(I) complex-promoted intramolecular cyclization reaction of β-keto trifluoromethyl amines has been developed, providing access to a series of unprotected trifluoromethylated aziridines with good chemical yields and excellent stereoselectivity...
