Benzylamine as Hydrogen Transfer Agent: Cobalt-Catalyzed Chemoselective C=C Bond Reduction of β-Trifluoromethylated α,β-Unsaturated Ketones via 1,5-Hydrogen Transfer
An efficient cobalt-catalyzed chemoselective reduction of β-CF3-α,β-unsaturated ketones using benzylamine as hydrogen transfer agent involving intramolecular 1,5-hydrogen transfer is reported. The reaction proceeded smoothly with a relatively w
Design and synthesis of 3-trifluoromethyl-3h-pyrazoles and further investigations of their transformation to 1h-pyrazoles
An efficient intramolecular cycloaddition strategy for the synthesis of trifluoromethyl-substituted 3H-pyrazoles was developed. Subsequently, their wide applications were demonstrated: they (1) react with dioxane by a radical process and (2) undergo [1,5] sigmatropic rearrangements. These applications are useful as the products were obtained in high yields and with excellent regioselectivity.
