Abstract

Aza-conjugate addition of phthalimide to 𝛼 , 𝛽 -unsaturated esters efficiently achieves in the presence of catalytic amount of C s 2 C O 3 and ionic liquid 1-butyl-3-methylimidazolium bromide ([bmim]Br) under mild reaction conditions ( 7 0 C ) to afford N-alkyl phthalimides in high yields and relatively short reaction times.
