carbonyl group, which is situated in the meta position of the methoxy substituent(s). This highly regioselective reaction (minimum: 95:5) is used as the key step in a short synthesis of daunomycinone (2a), 2-methoxy-7-deoxycarminomycinone (22b),γ-rhodomycinone (8), and 10-dexoy-γ-rhodomycinone (9). The products of the addition of 15 to 4a and 4b, the pseudoacids 16 are converted via the olefins 17 and
