A convergent route to indoloquinolines is developed through aldol condensation. This two-step method utilizes commercially available 2-oxoindole and o-nitrobenzaldehyde as starting materials. Chromatography-free method is accomplished for preparing several derivatives of indoloquinolines with desirable aromatic substitutions on indole as well as quinoline ring.

Synthesis of two linear indoloquinolines i.e. 6H-indolo[2,3-b]quinoline & 11-hydroxy-10H-indolo[3,2-b]quinoline, and spiro[2H-indole-2,3′- oxindole] from a common intermediate, (2-nitrophenyl)methylidene-dihydro- indolone derivative is described using microwave-mediated reductive cyclization as the key step. This journal is the Partner Organisations 2014.

experimental part, p. 6594 - 6596 (2012/01/03)
A short and convenient method for the synthesis of neocryptolepine (cryptotackieine) is described using Wittig reaction and one-pot reduction-cyclization-dehydration approach as the key steps.
Facile synthesis of 3-arylidene-1,3-dihydroindol-2-ones catalyzed by brnsted acidic ionic liquids
Hu, Yi,Kang, Hui,Zeng, Bi-Wen,Huang, He,Wei, Ping
experimental part, p. 263 - 267 (2009/04/11)
A series of 3-arylidene-1,3-dihydroindol-2-one derivatives were conveniently synthesized by the condensation of aromatic aldehydes with 1,3-dihydroindol-2-one using brnsted acidic ionic liquids as dual solvent-catalyst. This method has the advantages of s
