- 論文の詳細を見る
3-Phenyl-4<I>H</I>-benzo[<I>hi</I>]pyrrolo[2,1,5-<I>cd</I>]indolizin-4-one (<B>5</B>) was prepared by saponification accompanied by the decarboxylation of the corresponding 1,2-bis(methoxycarbonyl) derivative, which was obtained by the DDQ oxidation of 5,6-dihydro one. Investigations concerning its spectral data and MO calculations revealed interesting electronic features for <B>5</B>, e.g., i) a highly polarized structure in the ground state, ii) the exsistence of a peripheral [12]annulene system in acidic media, and iii) a significant stabilization of the excited state by protonation.
