## Abstract A cyclic secondary α‐amino acid, viz. L‐proline, reacts with isatin derivatives via decarboxylative azomethine ylide formation and subsequent cycloaddition with various dipolarophiles to give cycloadducts in moderate to good yield. Theoretical studies have been performed to study the st
