  On the reaction of (vinylimino)phosphorane and related compounds. 22. Syntheses and structural studies of methanocycloundeca[b]pyrrole ring systems

  摘要：

  Novel 2-phenyl-6,11- and 2-phenyl-4,9-methanocycloundeca[b]pyrroles (15a and 16a) were synthesized in moderate yields by the reaction of 3,8-methano[11]annulenone (3), a 10pi-electron vinylogue of tropone, with [(l-phenylvinyl)imino]triphenylphosphorane (8a) and subsequent dehydrogenation. Similarly, the reaction of the annulenone 3 with (inden-3-ylimino)tributylphosphorane (8c) and subsequent aromatization afforded 7,12- and 9,14-methano-15H-cycloundeca[b]indeno[2,3-d]pyrroles (15c and 16c), which also have methanocycloundeca[b]pyrrole ring systems. Preparation of 2-phenyl-5,10-methanocycloundeca[b]pyrrole (17), an isomer of both 15a and 16a, was also accomplished in low yield by the reaction of 4,9-methano[ll]annulenone (5) with an excess of [(1-phenylvinyl)imino]tributylphosphorane (8d). The reactivity of annulenone 5 with (vinylimino)phosphoranes was found to be quite low as compared to the higher reactivity of annulenone 3 and tropone. Compounds 15a,c, 16a,c, and 17 are the first nitrogen analogues of cyclopentacycloundecene ring systems which have vinylogous structures of 1-azaazulene. Structures of the products obtained were examined by H-1 NMR spectra and UV spectra. The H-1 NMR spectra clarified that the compounds 15a,c, 16a,c, and 17 are aromatic molecules having a diatropic 14pi-electron system, and 5,10-methano derivative 17 has a more diatropic nature than the compounds 15a,c and 16a,c. The UV spectra of 15a,c, 16a,c, and 17 exhibited increased cyclic conjugation of the aromatic perimeter according to a bathochromic shift of the longest absorption maxima as compared to the corresponding 1-azaazulene derivatives.
