  Resonance-stabilized α-naphthylmethyl carbocations and spiro compounds based thereon: VII. Transformations of α-naphthylmethyl carbocations stabilized by one electron-donor group or peri-fused heteroring

  摘要：

  1-Hydroxymethyl- and 1-alkoxymethylnaphthalenes containing dimethylamino and methoxy groups or a heteroring in positions 4 and 5 react with protic and Lewis acids to give 1-naphthylmethyl carbocations. Reactions of the latter with the initial alcohol molecule lead to the formation of oligomerization or dehydrogenation (to aldehyde) products or the corresponding dinaphthylmethanes. In some cases, the process was accompanied by cyclodimerization to form cyclohexadienone spiro derivatives in a small yield.

  摘要：

  Aminomethylation of 1,8-bis(dimethylamino) naphthalene ("proton sponge") afforded a series of its 4-dialkylaminomethyl-substituted derivatives. An attempt to introduce the second peri-dialkylaminomethyl group unexpectedly led to the formation of salts with the 2,2-dialkyl-6,7-bis(dimethylamino)-2-azonia-2,3-dihydrophenalene cation. The structure of one of these salts was established by X-ray diffraction analysis. Treatment of 1,8-bis(dimethylamino)-4-piperidinomethylnaphthale ne with iodomethane gave a spiro compound rather than the expected N-[4,5-bis(dimethylamino)-1-naphthylmethyl]-N-methylpiperidinium iodide. This spiro, compound was generated through cyclodimerization of the 1-naphthylmethyl carbocations. These transformations provide evidence that "proton sponge"-derived Mannich bases quaternized at the dialkylaminomethyl group are unstable and undergo the spontaneous transformation into the resonance-stabilized 4,5-bis(dimethylamino)-1-naphthylmethyl carbocation. By contrast, 4-dialkylamino-1 -dimethylaminomethylnaphthalenes gave methoiodides, which are stable under standard conditions. The latter compounds undergo the nucleophilic substitution of the NR3 group typical of such salts.
