base-mediated (3 + 2) cycloaddition of trifluoroacetohydrazonoyl chlorides with imidates for the construction of 3-trifluoromethyl-1,2,4-triazoles has been described. This reaction is characterized by readily starting materials, simple reaction conditions, good yields, a broad substrate scope, and excellent regioselectivity. The utility of this protocol has been validated by the synthesis of a drug-like

We describe the base-mediated [3 + 2] cycloaddition reaction of di/trifluoromethylated hydrazonoyl chlorides with fluoronitroalkenes for the synthesis of densely functionalized 3-di/trifluoroalkyl-5-fluoropyrazoles with potent biological activity.
Synthesis of fused 3-trifluoromethyl-1,2,4-triazoles <i>via</i> base-promoted [3 + 2] cycloaddition of nitrile imines and 1<i>H</i>-benzo[<i>d</i>]imidazole-2-thiols
Here we report a strategy for the facile assembly of fused 3-trifluoromethyl-1,2,4-triazoles, which are difficult to synthesize using traditional strategies, in 50–96% yields through a triethylamine-promoted intermolecular [3 + 2] cycloaddition pathway. This protocol features high efficiency, good functional group tolerance, mild conditions, and easy operation. Furthermore, a gram-scale reaction and
