A divergent approach to the myriaporones and tedanolide: completion of the carbon skeleton of myriaporone 1.
[reaction: see text] A linear but concise synthetic approach toward the structurally related natural products myriaporone and tedanolide is reported. The route is highlighted by a stereoselective homoallenylboration and a regio- and chemoselective nitrile oxide cycloaddition. Installation of the (Z)-olefin completed the carbon skeleton of myriaporone 1.
