With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.17057-04-4,4-(2,5-Dioxo-2,5-dihydro-pyrrol-1-yl)-benzoicacid,as a common compound, the synthetic route is as follows.
General procedure: An oven-dried flask was cooled under a stream of nitrogen and charged with azomethine N-oxide 1 (5 mmol), maleimide 2 (5 mmol) and sodium dried toluene (25 mL). The flask was equipped with a reflux condenser and the mixture was refluxed for 6 hrs (Scheme 3) until the substrates were consumed as judged by TLC. On completion the reaction mixture was concentrated and the precipitated compound was filtered. The crude product consists of a mixture of cis and trans isomers which was subjected to column chromatography over silica gel (100-200 mesh) using hexane: ethyl acetate (9:1) mixture as eluent.
The synthetic route of 17057-04-4 has been constantly updated, and we look forward to future research findings.
