Cycloaddition Reactions of Some Tricyclic Imides

Abstract

Our research group has published numerous papers over the last three years on the reaction of nitrile oxides and azomethine ylide with unsaturated tricyclic N-substituted dicarboximides selected according to the importance of possible biological activities. These reactions cover full range of mechanistic pathways and timings of bond-forming processes to give five-membered ring closure by 1,3-dipolar cycloaddition.
