Formal Total Synthesis of (-)-Dendrobine Using Zirconium-Promoted Reductive Cyclization
摘要:
The alkaloid (-)-dendrobine was synthesized from (+)-calvone by a short sequence using zirconium-promoted reductive cyclization. The absolute configuration of a synthetic intermediate was determined by an improved version of Mosher's method.
Formal Total Synthesis of (−)-Dendrobine Using Zirconium Promoted Cyclization. Determination of the Absolute Configuration of the Intermediary Tricyclic Ketone
The optical purity of (−)-dendrobine synthesized using zirconium promoted cyclization was improved and the absolute configuration of the intermediary tricyclic ketone was determined using the improved Mosher’s method developed by Kusumi.
