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, 22.5 mg (20 mumol) of Intermediate 101 were taken up in 2 ml of 1:1 dioxane/water and then admixed with 5.6 mg (40 mumol) of methyl 2,5-dioxo-2,5-dihydro-1H-pyrrole-1-carboxylate and with 0.25 ml of saturated sodium hydrogencarbonate solution. The reaction mixture was stirred at RT for 30 min. Then another 0.25 ml of the saturated sodium hydrogencarbonate solution was added and the reaction mixture was stirred at RT for a further 15 min and then concentrated under reduced pressure. The remaining residue was purified by means of preparative HPLC. After lyophilization, 12.8 mg (50% of theory) of the title compound were obtained as a colourless foam. [1945] HPLC (Method 5): Rt=1.9 min; [1946] LC-MS (Method 1): Rt=0.95 min; MS (ESIpos): m/z=1019 (M+H)+.
55750-48-6 Methyl 2,5-dioxo-2,5-dihydro-1H-pyrrole-1-carboxylate 580610, apyrrolines compound, is more and more widely used in various fields.
