The revision of the structure of haemofluorone B to 5,8,9-trihydroxy-3H-naphthoxanthen-3-one is confirmed by the synthesis of its trimethyl ether by photochemical oxidative cyclization of 9-(3,4-dimethoxyphenyl)-4-hydroxy-2-methoxy-1H-phenalen-1-one.The conventional process for conjugate arylation of phenalenones has been improved by the use of aryllithium reagents.
