The conformations of E-2-phenyl-3(2′-furyl)propenoic acid and its methyl ester were investigated by NMR spectroscopy. Applying various solvents (methanol, chloroform and dimethyl sulfoxide) the possible conformers in solutions were studied by two-dimensional NOESY measurements. Irrespective to the solvents and whether the investigated moiety was the ester or the acid dimer, no conformational preferences could be identified experimentally.

Four new N-(p-chlorophenyl)carboxamides 1 - 4 of 9-phenanthrene-, 5-naphthofuran-, and 5-naphtho- and 4-naphthothiophenecarboxylic acids have been synthesized.All carboxanilides were exposed to UV oxidative irradiation in methanolic solution.In the case of 2 and 3 corresponding benzo-furophenanthridin-10(9H)-one 5 and benzo-thienophenanthridin-10(9H)-one 6 are isolated.
