  Studies directed to the synthesis of new C-5 spiroannulated julolidines

  摘要：

  Two series of new 7,9-disubstituted spirojulolidines 8a-d and 10a-e were synthesized by acid catalyzed intramolecular cyclization of N-(3-chloropropanoyl) spirodihydroquinolines 5a-d and N-carbethoxymethyl spirodihydroquinolines 7a-e using AlCl3 and PPA, respectively. The spectroscopic analyses of intermediate compounds and the final spirojulolidines were discussed. (C) 2002 Elsevier Science Ltd. All rights reserved.

  A series of N-carbethoxymethyl spirotetrahydroquinolines (6) were prepared and subjected to cyclization. We show that cyclization of (6) in the presence of excess PPA results in a 50–62% yield of unexpected spirojulolidines (7).

  The transformation of N-substituted 3,4-dihydrospiro[quinoline-2,1'-cyclohexanes] 2 and 3 has been examined in strong acid media, at elevated temperature. It was demonstrated that the N-(gamma-cyanopropyl) spirodihydroquinolines 2 in the presence of concentrated sulfuric acid or PPA underwent hydrolysis affording the gamma-aminoacids 3. The spirodihydroquinoline ring rearrangement readily produces 4-(2-oxopyrrolidinyl-1)spiro[indane-1,1'-cyclohexanes] 5 in good yields. The structures of all synthesized compounds were established by means of homonuclear and inverse-detected 2D NMR experiments. (C) 2003 Elsevier Science Ltd. All rights reserved.
