Synthesis of bulky 2,2-diaryl-1,2-dihydro-3H-indol-3-ones via singlet oxygenation of 2-arylindoles
Ke-Qing, Ling
, p. 149 - 152 (1996)
2,2-Diaryl-1,2-dihydro-3H-indol-3-ones (2a-2j) have been synthesized via singlet oxygenation of 2-arylindoles (1a-1d), followed by acid-catalyzed nucleophilic substitution of the resulting 2-aryl-2-methoxy-1,2-dihydro-3H-indol-3-ones (3a-3d) with aryl nuc

An asymmetric normal-electron-demand aza-Diels-Alder cycloaddition of 2-aryl-3H-indol-3-ones and 2,4-dienals was explored via trienamine catalysis of a chiral secondary amine. Multifunctional tricyclic polyhydropyrido[1,2-a] indoles were efficiently constructed in good stereoselectivity (up to 92% ee, >19:1 dr).
Facile synthesis of 2-aryl-3H-indol-3-ones via singlet oxygenation of 2-arylindoles
Ling

2-Aryl-3H-indole-3-ones have been synthesized via singlet oxygenation of 2-arylindoles in methanol followed by thermodemethoxylation of the resulting 2-aryl-2-methoxy-1,2-dihydro-3H-indol-3-ones in one pot in good yields.
