Synthesis of 2-acyl- and 2-benzoylindoles

2-Nitrobenzaldehydes (3a–c) on reaction with phosphoranes (4a and 4b), and triphenyl phosphine in refluxing diphenylether provide 2-acylindoles (6a–c) and 2-benzoylindoles (6d–f). Alternatively 2-nitrobenzaldeydes (3a–c) on reaction with phosphoranes (4a and 4b) give nitroketones (5a–f) which on ref...

Summary:2-Nitrobenzaldehydes (3a–c) on reaction with phosphoranes (4a and 4b), and triphenyl phosphine in refluxing diphenylether provide 2-acylindoles (6a–c) and 2-benzoylindoles (6d–f). Alternatively 2-nitrobenzaldeydes (3a–c) on reaction with phosphoranes (4a and 4b) give nitroketones (5a–f) which on refluxing with triphenyl phosphine in refluxing diphenyl ether furnish 2-acyl- and 2-benzoylindoles (6a–f).
