A short, convergent synthesis of the mushroom pigment norbadione A is described. The construction ofan appropriately substituted naphtholactone intermediate involved a regioselective Diels-Alder reactionbetween a bis(triisopropylsilyloxy)diene and 2,6-dichlorobenzo-1,4-quinone. A double Suzuki-Miyauracross-coupling between a diboronate and two identical enol triflates was another key feature of thesynthesis.
