Abstract
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 tri- and tetracyclic quinone intermediates. The -7-deoxydaunomycinone derived from naturally occurring daunomycin is a known compound, which is itself an intermediate in the preparation of the clinically accepted anti-tumor antibiotics daunomycine and its derivative adriamycin.
