• To establish a novel synthetic strategy for accessing the narceine imide core structure.

Main Methods:

• Sequential construction of the isoindolinone template.
• Metalation and coupling with an isoquinolinium salt.
• E1cb elimination for arylmethylene unit formation and dimethylaminoethyl chain construction.

Main Results:

• A concise and efficient total synthesis of alkaloid narceine imide was achieved.
• The key steps included isoindolinone template construction, metalation-coupling, and E1cb elimination.
• The synthesis successfully formed the arylmethylene unit and the dimethylaminoethyl chain.

Conclusions:

• The developed synthetic route provides an efficient access to alkaloid narceine imide.
• This methodology can be valuable for the synthesis of related natural products and drug discovery efforts.
