Disclosed herein is a highly efficient one-pot synthetic strategy to phenanthrone-type polyheterocycles via tandem rhodium(III)-catalyzed ortho-C-H heteroarylation of indolyl ketones and copper(II)-promoted intramol. cyclization. This protocol enables a library of blue-emitting fluorophores with high quantum yields and narrow full widths at half-maximum to be rapidly built from readily available substrates, among of which 6,6,7,9,12-pentamethyl-6,12-dihydro-5H-benzofuro[2,3-a]carbazol-5-one exhibits pure blue emission with Commission Internationale de I’Eclairage coordinates of (0.15, 0.09) and a high quantum yield of 85% in CH2Cl2 solution
Organic Letters published new progress about C-H bond activation. 93247-78-0 belongs to class indole-building-block, and the molecular formula is C10H9NO2, Synthetic Route of 93247-78-0.
