Abstract A practical BF3·OEt2-catalyzed regioselective 1,2-addition or 1,4-hetero-Michael addition of oxygen, sulfur, and nitrogen nucleo philes to maleimides has been developed for the synthesis of alkyl fumarate derivatives or 3-su

N-Arylmaleimides and N-arylsuccinimides were prepared by dehydrochlorination reaction of N-aryl α-chlorosuccinimides in the presence of a base and by reduction of 2-chlorosuccinimide in the presence of zinc, respectively. N-Aryl α-chlorosuccinimides were obtained by dehydration of N-aryl substituted maleamic acids in the presence of thionyl chloride. The structure of the synthesized compounds was confirmed by IR, 1H-NMR and 13C-NMR spectra.

N-substituted monochlorosuccinimides e.g., N-phenylmonochlorosuccinimide, can be prepared in a high yield by reacting a maleamic acid, e.g., N-phenylmaleamic acid, with phosgene in the presence of a catalyst, e.g., dimethylformamide.
