CuI-catalyzed photochemical or thermal reactions of 3-(2-azidobenzylidene) lactams. Application to the synthesis of fused indoles

Photochemical or thermal reactions of 3-(2-azidobenzylidene)-lactams afforded fused indoles such as indolo[3,2-c]quinolin-6-ones, pyrido[4,3-b]indol-1-ones and other similar compounds in moderate to high yields via cyclization-ring expansion reactions. Th

A Convenient Synthesis of 11H-Indoloquinolones

11H-Indoloquinolin-6-ones, which are containing the γ-carboline ring system, can be easily synthesized from 4-azido-3-phenyl-2(1H)-quinolones, which are obtained in a two step reaction from 4-hydroxy-3-phenyl-2(1H)-quinolones.Cyclization of the azi

Methods for the Synthesis of 4-Azido-2(1H)-quinolones

4-Hydroxy-2-quinolones 1 are generally found to be converted to the 4-azidocompounds 3 via the 4-chloroquinolones 2, the 4-tosyloxyquinolones 6, or the 4-aminoquinolones 4, respectively.Choice of the reaction conditions and yields depend on the substituen

Synthesis of Indoles and Isoquinolones from Phenylmalonate Heterocycles

A new synthesis of the indole system has been achieved by cyclodehydrogenation of amino phenylmalonate heterocycles.Thus, the 4-amino coumarins 1a,b or the 4-amino-2-quinolones 1c-g are converted to the indoles 2 with palladium on charcoal in boiling diph
