novel prenylated naphthoquinone antibiotic, was synthetized from ethyl acetoacetate in three steps (58% overall yield). The key step of the synthesis is the construction of the naphthoquinone skeleton by a regioselective Diels−Alder reaction between a 2-alkyl 1,3-bis(trimethylsilyloxy)-1,3-diene derivative and a bromoquinone. This short and versatile approach confirms the structure of fumaquinone and
