Here, we report 5-hydroxy-1,2,3,4,4a,9a-hexahydro-1,4-ethano-9,10-anthraquinone (13), a small molecule generating reactive oxygen species (ROS) in pH 7.4 buffer under ambient aerobic conditions that has selective and potent Mycobacterium tuberculosis growth inhibitory activity.

(+/-)-Daunomycinone and (+/-)-4-demethoxydaunomycinone have been synthesized via two successive Diels-Alder reactions from naphthazarin. Key steps for the construction of the A-ring of the anthracyclinone are the Diels-Alder reaction of the BCD fragments with 1-tert-butoxy-3-trimethylsilyloxybuta-1,3-diene and further functionalisation of the hydrolysed product with trimethylsilylethynyl lithium, these
