Reaction Conditions:

in acetonitrile at 20; for 8 h;Mechanism;

Steps:

4.3. General synthetic procedure for the pyrrolizidinones 23, 24, pyrrolo[1,2-a]azepinones 20, 21, succinimides 18, 19, 22, and 25

General procedure: A solution of heterocyclic enaminone 12a,b,d (1.0 mmol) and maleimide 2a-c (1.0 mmol) in the solvent (5.0 mL), temperature and time indicated in each case, was magnetic stirring.
