There is provided a novel method of synthesizing certain tetracyclic quinones. In particular, there is provided a novel route to the synthesis of (.+-.)-7-deoxydaunomycinone and analogs thereof which includes the provision of novel tetrahydronaphthoquinones and tetracyclic quinone intermediates. The compounds of the present invention are provided through a route comprising a Diels-Alder addition of certain isobenzofurans to certain novel tetrahydronaphthoquinones. The products of the synthetic route provided herein may be converted into compounds of known antibiotic and antineoplastic activity.
