in the synthesis of anthracyclinones via two approaches which differ by beginning at opposite ends of the molecule with either an aryl or an alkenyl substitutedchromium carbene complex. The latter has been employed in a formal synthesis of daunomycinone. The Diels-Alder reactions of α,β-acetylenic chromium carbene complexes provide for a facile entry into substituted cyclohexenyl chromium carbene
