Abstract

Cyclic imide derivatives constitute an important class of chemically, biologically and pharmaceutically significant compounds.1 Despite their wide applicability, available routes for their synthesis are somewhat limited. Generally, most methods involve Lewis acid mediated condensation of an amine with the appropriate cyclic acid anhydrides,1c,2a,2c and cyclisation of the N-substituted amic acid in the presence of acidic reagents.2b Direct N-alkylation under Mitsunobu ...
