A total synthesis of the Calceolaria andina L. extract 2-(1,1-dimethyl-2-propenyl)-3-hydroxy-1,4-naphthalenedione is described incorporating the first reported D?tz benzannulation of a selenoalkyne. Importantly, it has been shown that it is possible to effect this annulation at ambient temperature under dry state conditions with a significant improvement in cyclisation yield.
