11-Deoxydaunomycinone (1b) has been synthesized via nucleophilic addition to the alicyclic part and directed lithiation at the aromatic part in the (η6-arene)tricarbonylchromiumcomplexes of the hydronaphthalene derivatives.

Preparation of 9-acetyl-6-hydroxy-4-methoxy-7,8,9,10-tetrahydronaphthacene-5,12-dione (the object intermediate), and precursor compounds to the object intermediate. Preparation of the object intermediate according to the invention begins from 2-(2-hydroxyethyl)-bicyclo[2.2.2]oct-5-ene, wherein the latter is converted to 6-acetyl-4a,5,6,7,8,8a-hexahydro-1(4H) naphthalenone (one of the two precursor compounds) which is subsequently reacted with a phenylsulfonyl isobenzofuranone to furnish, regiospecifically, 9-acetyl-5,12-dihydroxy-4-methoxy-6(11H)-hexahydronaphthacenone (the other of the two precursor compounds). Heating the hexahydronaphthacenone in dimethylforamide under an oxygen atmosphere gives the object intermediate.
