How is 1-Allyl-1H-pyrrole-2,5-dione (CAS: 2973-17-3) typically synthesized?

1-Allyl-1H-pyrrole-2,5-dione can be synthesized through a condensation reaction between pyrrole and allyl alcohol. Commonly, this involves the use of acid catalysts such as p-toluenesulfonic acid (p-TSA) or sulfuric acid. The reaction typically proceeds with good selectivity and moderate to high yield. The process is carried out under mild conditions, ensuring the formation of the desired product with minimal side reactions.
