Interpretation of the chemical and spectral (IR., UV., 1 H‐ and 13 C‐NMR.) properties of the antitumor antibiotic hedamycin (C 41 H 50 N 2 O 11 ) suggests that the molecule contains a methyl substituted 1‐hydroxyanthraquinone nucleus, an α, β‐unsaturated ketone, two sugar‐like tetrahydropyran rings ( 4 and 8 ) and an aliphatic chain 2 , presumably with an epoxy group (see the Scheme ).
