The strong base induced cycloaddition of homophthalic anhydrides and relatedcompounds to halo- 1,4-naphthoquinone derivatives has been shown to provide short convergent syntheses of anthracyclinones, 4-demethoxydaunomycinone (1), daunomycinone (2), 11-deoxydaunomycinone (3), and 11-deoxycarminomycinone (4).
