Total chemical synthesis and antitumor evaluation of 4-demethoxy-10,10-dimethyldaunomycin

The novel anthracycline analogue 4-demethoxy-10,10-dimethyldaunomycin was prepared in nine chemical steps from 5,8-dimethoxy-2-tetralone. It proved to be inactive as an antitumor agent in the mouse P388 lymphocytic leukemia model.
