Kumar, Abhishek published the artcileCopper(II)-catalyzed decarboxylative cyclization for accessing biologically relevant 3-(2-furanyl)indoles from 3-cyanoacetyl indoles and cinnamic acids, Recommanded Product: (E)-3-(2,4-Dimethoxyphenyl)acrylic acid, the publication is Tetrahedron (2020), 76(36), 131433, database is CAplus.
A novel and efficient route for the synthesis of 3-(2-furanyl)indoles I (R1 = H, Me, Et; R2 = H, Me; R3 = 6-Cl, 5-OMe, 5-F, etc.; R4 = Ph, 2-BrC6H4, 1-naphthyl, etc.) from readily available 3-cyanoacetyl indoles and ¦Á,¦Â-unsaturated carboxylic acids via Cu(II)-catalyzed decarboxylative, intermol. annulation is reported. In this transformation, di-tert-Bu peroxide was used as an external oxidant. This reaction underwent radical addition, decarboxylative processes, and provides a facile regioselective 3-(2-furanyl)indole derivatives in good to excellent yields.
