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: Equimolar quantities of maleimide (2) and nitrones (5a-k and 6a-k) were refluxed in toluene (20 ml) and ethyl alcohol (5 ml) for 8-10 h (TLC monitoring using petroleum ether and hexane 1:1) followed by cooling with addition of dry ether. The products (7a-k and 8a-k) were separated out after filtration and recrystallized from toluene and petroleum ether mixture (1:1) to yield cis-isomers (7aa-7ka and 8aa-8ka). The mother liquor on further work up provided trans-isomers which were recrystallized from ethanol and diethyl ether mixture (1:1) (7aa’-7ka’ and 8aa’-8ka’) (Fig. 3).7 These stereoisomers were characterized by their 1H NMR, IR and mass spectra in addition to their melting points and elementary analysis. These stereoisomers have identical IR spectra and elemental analysis but differ in their melting points, 1H NMR and mass spectra., 17057-04-4

The synthesis of ACPM was performed essentially according to the method described in the patent [35]. The typical synthetic procedure is as follows: To a solution of CPMI (3.01 g, 13.9 mmol) and TEA (2.0 mL) in toluene (100 mL) was added DPPA (3.00 mL,13.9 mmol), and the resulting solution was stirred at room temperaturefor 48 h. After the reaction mixture was evaporated in vacuo, an oily residue was flash chromatographed over activated silica using chloroform as an eluant. The eluate was evaporated in vacuo to give ACPM as a yellow solid (2.86 g, 85.1%)., 17057-04-4

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.
