NEW SYNTHETIC "TRICKS". ONE-POT PREPARATION OF N-SUBSTITUTED PHTHALIMIDES FROM AZIDES AND PHTHALIC ANHYDRIDE

Article abstract of DOI:10.1016/S0040-4039(00)84061-7

N-Substituted phthalimides can be obtained in very good yields, under essentially neutral conditions, by mixing or heating an alkyl (or aryl) azide, triphenylphosohine, and phthalic anhydride in benzene or toluene, in the presence of a catalytic amount of tetrabutylammonium cyanide.Application of the reaction into the domain of carbohydrates is promising.
