  New Syntheses of Di-π-Substituted Heptalenes

  摘要：

  To study the effect of double-bond shifts (DBS) in different type of heptalenes linked to extended pi- systems, several di-pi-substituted heptalenes were synthesized. 6-[(E)-Styryl]heptalene-dicarboxylate 4 was smoothly converted to 1-(chloromethyl)heptalene-dicarboxylate 5 by treatment with t-BuOK and C2Cl6 in THF at -78 degrees. The one-pot reaction of 5 and P(OEt)(3) in the presence of NaI, followed by Wittig-Horner reaction, afforded the 1,6-di-pi-substitute heptalene 6. The reaction of 6-[(1E,3E)-4-phenylbuta-1,3-dienyl]heptalenes 7 or 15 with t-BuOK and benzaldehyde in THF led to the formation of the 1,6-di-pi-substituted heptalenes 13 or 16, together with transesterification products 14 or 17. The transformation of the MeOCO group at C(4) of 6-[(E)-styryl]heptalene-dicarboxylate 4 to a phenylbuta-1,3-dienyl substituent afforded the 3,6-di-pi-substituted heptalene 21a, which is in thermal equilibrium with its DBS isomer 21b in solution. Oxidation of heptalene 22 with SeO2 in dioxane gave carbaldehyde 23, which was then subjected to a Wittig reaction to give the 6,9-di-pi-substituted heptalene-dicarboxylate 24.

  are formed, the corresponding benzanellated azulene trans-29 ist found to be the second main product (21 and 10%, respectively) under both reaction conditions. The thermal reaction yields also the benzanellated azulene 28 which is not found in the catalyzed variant of the reaction. Heptalene-1,2-dicarboxylates are also formed from 4-[(E)-styryl]azulenes (e.g. (E)-33 and (E)-34; Scheme 14) and ADM at
