title: Total syntheses of echinopines.
abstract: A concise and scalable synthesis of a cis-fused bicyclo[5.3.0]decane ring system has been developed for the total synthesis of echinopines. The core of the natural products was constructed efficiently through an intramolecular 1,3-dipolar cycloaddition and ring contraction strategy.
