1122-10-7, 3,4-Dibromo-1H-pyrrole-2,5-dione is a pyrrolines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
3,4-dibromo-N-methyl ester maleimide was synthetized from the corresponding 3,4-dibromomaleimide by adapting the procedure disclosed by Castaeda et al. in Tetrahedron Lett. 2013, 54, 3493-3495.3,4-dibromomaleimide (5 g, 19.92 mmol) was dissolved in THE (175 ml). N-methylmorpholine (2.16 ml, 19.92 mmol) and methyl chloroformate (1.51 ml, 19.92 mmol) were added at room temperature under argon. The reaction mixture was stirred at room temperature under argon for 20 mm, then diluted with DCM (200 ml). The organic layer was washed with water (200 ml), dried over MgSO4, concentrated and lyophilized to yield 6.15 g (100%) of product.[00252] 1H NMR (500 MHz, CDCI3): 5= 4.01 (5, 3H). 130 NMR (126 MHz, CDCI3): 5= 159.23, 146.91, 131.41, 54.79., 1122-10-7
As the paragraph descriping shows that 1122-10-7 is playing an increasingly important role.
