Uses
N-Benzylmaleimide is used as plastic additive, Pharmaceutical Intermediates. It is an important raw material intermediate used in organic Synthesis, Pharmaceuticals, Agrochemicals Dyestuff.
General Description
N-Benzylmaleimide is an N-substituted maleimide and its microwave-mediated facile and fast synthesis has been described. Radical and anionic copolymerization of N-benzylmaleimide with optically active N-(L-menthoxycarbonylmethyl)maleimide has been reported. Base-catalyzed asymmetric cycloaddition of anthrone with N-benzylmaleimide was studied in the presence of C2-chiral pyrrolidines. Stereoselctive iridium-catalyzed double incorporation reaction of styrene with N-benzylmaleimide affords cyclic product.
Synthesis
108-31-6
100-46-9
1631-26-1
GENERAL PROCEDURE: At room temperature, benzylamine (17 mmol) was slowly added dropwise to a solution of maleic anhydride (20 mmol) dissolved in acetic acid (10 mL) to form a suspension. Subsequently, the reaction mixture was stirred under reflux conditions overnight. Upon completion of the reaction, the solvent was removed by distillation under reduced pressure. The residue was dissolved in chloroform (100 mL) and extracted by partition with deionized water (30 mL). The aqueous phase was further extracted with chloroform (3 x 50 mL). All organic phases were combined and washed sequentially with saturated aqueous sodium bicarbonate (30 mL) and brine (30 mL). The organic phases were dried over anhydrous sodium sulfate, filtered and concentrated. Finally, the concentrated residue was purified by silica gel column chromatography to obtain N-benzylmaleimide.
