Abstract：Isoindoline 1-one has been widely studied in many natural products, pharmaceuticals, and biologically active molecules due to its specific nitrogen containing structural framework. Using o-carboxyacetophenone and tryptamine as starting materials, N-tryptamine 3-alkenylisoindolinone skeleton compound was obtained through two-step dehydration and cyclization under the catalysis of p-toluenesulfonic acid. The operation was simple, and the final target product was obtained in excellent yield(57%~81%). The structure of all products were confirmed by 1H NMR, 13C NMR and HR-MS(ESI).
