55750-48-6, Methyl 2,5-dioxo-2,5-dihydro-1H-pyrrole-1-carboxylate is a pyrrolines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,55750-48-6
Using a 40 mL vial, a solution of prop-2-yn-1 -amine (500 mg, 9.08 mmol) in 15 mL of sat. aqueous NaHCO3 was cooled to 0 C with ice bath and then methyl 2,5-dioxo-2,5-dihydro-1 H-pyrrole-1 -carboxylate (1 .27 g, 8.17 mmol) was added. The reaction mixture was then stirred at the same temperature for 4 h and then extracted wtih 50 mL of CH2CI2 three times. The combined organic layers were dried over Na2SO4, concentrated, purified by ISCO (24 g, silica gel) and concentrated to give 1-(prop-2-yn-1-yl)-1H-pyrrole- 2,5-dione (i-3). 1H-NMR (CDCI3, 400 MHz) O 6.76 (s, 2H), 4.29 (d, 2H, J = 2.8 Hz), 2.21(t, 1H, J=2.8 Hz).
As the paragraph descriping shows that 55750-48-6 is playing an increasingly important role.
