ABSTRACT
Herein, we report a formal synthesis of (±)-arborisidine via the creation of Jiao's intermediate with the critical caged structure. Starting from tryptamine, a Pictet-Spengler cyclization forged the piperidine ring, a Pd-catalyzed indole allylation and ring-closing metathesis protocol afforded a bridged aza-bicyclo[3.3.1]nonane moiety, and an intramolecular N-alkylation closed the final pyrrolidine ring. This study provides a new approach to the unique caged framework of arborisidine and relevant alkaloids.
