| Abstract: | The reactions of various I-acyloxyanthraquinones with benzyl cyanide in DMSO in the presence of K2CO3 were studied. 1-Phenyl-6H-anthra1,9-b,c]furan-6-one derivatives are formed as the main reaction products. In the case of unsubstituted I-acyloxyanthraquinones, 1-phenyl-6H-anthra1,9-b,cfuran-6-one and I-phenylanthra1,9-b,clpyran-2,l-dione were isolated. It was shown that furanoanthrones can be synthesized in two steps via the corresponding pyronoanthrones.Translated fromlzvestiya Akademii Nauk.
