Yield:1604038-33-6 99%

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. After this, the reaction mixture was concentrated under reduced pressure and the residue was purified by column chromatography on silica gel when necessary.
