Azomethine Ylide Cycloaddition Approach toward Dendrobine: Synthesis of 5-Deoxymubironine C.
A concise route to the azatricyclo[6.2.1.04,11]undecane core of (−)-dendrobine and (−)-mubironine C is described wherein an unstabilized azomethine ylide cycloaddition provides the complete carbon framework of the natural products.
