| Popis | Syntheses of carbocyclic analogs of dehydroaltenusin tautomers are reported. Both target compounds, cDHA (2,8-dihydroxy-6-methoxy-10a-methyl-10,10a-dihydrophenanthrene-3,9-dione) and cDHAs (4,5-dihydroxy-6-methoxy-2-methylspiro[cyclohexa[2,5]diene-1,1-indene]-3,4(2H)-dione), were prepared from 3,5-dimethoxybenzaldehyde in 11 and 13 steps, respectively. Unlike dehydroaltenusin, both cDHA and cDHAs are stable and their structures were confirmed by X-ray crystallography. Compound cDHA was found to be active against calf DNA polymerase a but not related isozymes, while the spirocyclic analog cDHAs was inactive. |
