The total synthesis of (-)-thysanone is described. The key step involves the addition of an o-toluate anion to a lactone to create the naphthopyran framework (Staunton-Weinreb annulation). This synthesis further confirms the absolutestereochemistry of the natural product to be 1R,3S. thysanone - Staunton-Weinreb annulation - total synthesis - natural products - polycycles
