摘要:
The synthesis of a novel thiophene isoster of aceanthrylene is reported. The sequence involves, a newly observed regiospecific condensation of oxalylchloride to naphtho[2,3-b]thiophene. Reduction of the quinone and dehydrogenation gave the title compound in 28% overall yield. The proton nmr signals of the title compounds were assigned on the basis of COSY and NOE difference spectroscopy. Its isolectronic nature with aceanthrylene is seen in the similarity of the UV spectra.
