17057-04-4, 4-(2,5-Dioxo-2,5-dihydro-pyrrol-1-yl)-benzoicacid is a pyrrolines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,17057-04-4
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.
The synthetic route of 17057-04-4 has been constantly updated, and we look forward to future research findings.
