The synthesis of racemic tetrangomycin (11) is reported. In the key step the hexahydrobenz[α]anthraquinone 8 is generated in a regioselective Diels‐Alder reaction of diene 5 with bromonaphthoquinone 7. The conversion of 8 into 11 involves only three operations: treatment with diethyl ether–boron trifluoride, hydrogen peroxide and photooxygenation.
