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.

Total synthesis of (-)-renieramycin G from l-tyrosine

(-)-Renieramycin G was synthesized in 21 steps for the longest linear sequences employing l-tyrosine methyl ester as the chiral starting material in 8.5% overall yield. Two of the four chiral centers came from l-tyrosine methyl ester, and the other two we
