A FACILE CONSTRUCTION OF THE WOODWARD KETONE BY A ZIN(II) CHLORIDE-CATALYZED STILLE COUPLING REACTION

摘要

The pentacyclic ketone,obtained by Woodward and co-workers during the first total synthesis of strychnine,has been prepared in a five-step sequence form 2-methyltryptamine by employing a zinc(II) chloride-catalyzed Stille coupling reaction as the key step.
