Catalytic Asymmetric 1,6-Michael Addition of Arylthiols to 3-Methyl-4-nitro-5-alkenyl-isoxazoles with Bifunctional Catalysts

, 2011
An enantioselective 1,6-Michael addition reaction of arylthiols to a wide range of 3-methyl-4-nitro-5-alkenyl-isoxazoles catalyzed by readily available Takemoto's thiourea catalyst has been developed.

Visible-Light-Mediated Three-Component Strategy for the Synthesis of Isoxazolines and Isoxazoles

Isoxazolines and isoxazoles commonly serve as core structures of many therapeutic agents and natural products. However, the metal-free and catalysis-free strategy for the synthesis of these privileged motifs at room temperature remains a challenging task.
