The Reissert indole synthesis is a series of chemical reactions designed to synthesize indole or substituted-indoles (4 and 5) from ortho-nitrotoluene 1 and diethyl oxalate 2. Potassium ethoxide has been shown to give better results than sodium ethoxide. See more The first step of the synthesis is the condensation of o-nitrotoluene 1 with a diethyl oxalate 2 to give ethyl o-nitrophenylpyruvate 3. The reductive cyclization of 3 with zinc in acetic acid gives indole-2-carboxylic … See more • Leimgruber-Batcho indole synthesis See more Butin modification In an intramolecular version of the Reissert reaction, a furan ring-opening provides the … See more WebSep 15, 2010 · The multistep synthesis of indole derivatives from ortho -nitrotoluene involving the basic condensation of o -nitrotoluene with oxalic ester to o …
