Azomethine Ylide Cycloaddition Approach toward Dendrobine: Synthesis of 5-Deoxymubironine C

Benjamin M. Williams, Dirk Trauner

Research output: Contribution to journalArticle


A concise route to the azatricyclo[,11]undecane core of (-)-dendrobine and (-)-mubironine C is described wherein an unstabilized azomethine ylide cycloaddition provides the complete carbon framework of the natural products. The cyclization precursor is made in short order from (R)-carvone through an unconventional high-pressure Ireland-Claisen reaction. Attempts to install a final hydroxyl group through an intramolecular lactonization strategy and the observation of an unexpected and highly complex enal-ene product are also reported.
