A convergent AB + CD route to daunomycinone (1) is described. The AB segment is synthesized from the Diels–Alder adduct (3) of an isobenzofuran and methyl vinyl ketone by means of an unusual 5-endo–trig cleavage (3 → 4). The CD half (9) is combined with the AB by the Kraus annelation technique to provide a 9-deoxy daunomycinone derivative (12a) which is subsequently oxygenated.
