  Effect of 1,4-naphthoquinone annelation on the conformational behavnniour of carbonyl- and methano-bridged cyclodecadiene derivatives

  摘要：

  The Na2Cr2O7 oxidation of hexahydro-7,16-methanodinaphtho[2,3-a:2',3'-f] cyclodecene derivative 2, produced two bis-(1,4-naphthoquinone)s, 7 and 9, and monoquinone compound 8. Benzonaphtho derivative 3 gave two 1,4-naphthoquinone derivatives, 10 and 11, on oxidation.Flexible compounds 7-11 showed temperature-dependent H-1 NMR spectra due to equilibria among chair-boat, twin-chair, and boat-chair conformers, which were H-1 NMR spectroscopically characterized. A twin-chair conformer was detected in products 8, 9 and 10, but not in compounds 7 and 11. A broad absorption band due to an intramolecular C-T interaction in the twin-chair conformer was observed at lambda approximately 400 nm in the electronic spectra of the monoquinones, 8 and 10, but not in the bis(quinone) 9. Population of the twin-chair conformer increased with removal of the ester group on the bridgehead position. Reduction of the carbonyl group on the bridge also favoured the twin-chair conformation, indicating a repulsive interaction between the ester and the carbonyl group of the 1,4-naphthoquinone moiety. Upon irradiation with sunlight, compound 7 gave the [2 + 2]-photoadduct 15.
