Synthetic study toward ecteinascidin 743: Concise construction of the diazabicyclo[3.3.1]nonane skeleton and assembly of the pentacyclic core

(Figure Presented) Synthesis of the pentacyclic core of ecteinascidin 743 is described. This synthesis features concise construction of the diazabicyclo[3.3.1]nonane skeleton using gold(I)-catalyzed one-pot keto amide formation, acid-promoted enamide formation, and oxidative Friedel-Crafts cyclization as the key steps.
