  Medium-sized cyclophanes. Part 21. Preparation and reduction of syn- and anti-[3.2]metacyclophanequinone and anti-[4.2]metacyclophanequinone

  摘要：

  The title compounds, anti- and syn-[3.2]metacyclophanequinone (12a) and (12b), were prepared by oxidation of the corresponding anti- and syn-9,17-dihydroxy-6,14-di-tert-butyl[3.2]metacyclophanes (10a) and (10b) with Tl(OCOCF3)3 in CF3COOH. When anti-13.2]quinonophane (12a) was reduced with Zn powder in acetic acid, the corresponding tetrahydroxy derivative 14a was obtained, which was converted to the quinhydrone 13a by treatment with an equimolar amount of quinonophane 12a in refluxing THF. The electronic spectrum of 13a shows a band due to a charge-transfer complex at 400 nm (log-epsilon 2.45). In contrast, attempted reduction of syn-quinonophane (12b) with Zn powder in acetic acid yielded only a complex mixture of products. It was also found that syn-quinonophane was easily converted to the corresponding [2 + 2] cycloadducts 16 and 17 by irradiation with sunlight or tungsten lamp. When oxidation of anti- and syn-10,18-dihydroxy-7,15-di-tert-butyl[4.2]-metacyclophanes (11a) and (11b) with Tl(OCOCF3)3 in CF3COOH was carried out under the same conditions as [3.2]metacyclophanes, both compounds gave anti-metacyclophanequinone (18a). This finding suggests that the ring inversion to the thermodynamically more stable anti conformation is possible in the [4.2]metacyclophanequinone. While anti-[4.2]metacyclophanequinone (18a) was reduced with Zn powder in acetic acid, the color change of reaction mixture from pale yellow to reddish brown was observed due to the formation of the corresponding quinhydrone 19. However, the attempted isolation of the quinhydrone 19 was unsuccessful. Rather, the fully reduced tetrahydroxy derivative 20 was obtained in 91 % yield.

  intramolecular O–C coupling product 2, which has a spiro skeleton in good yield; variable temperature 1H NMR measurements indicated that compounds 2 are interconvertible by a thermal [3.3] sigmatropic rearrangement, and the activation free energies for the [3.3] sigmatropic rearrangement increased with increasing length of the methylene bridge in compounds 2.

  用K 3 [Fe（CN）6 ]氧化二羟基[ n .2]甲基环已烷1可以得到分子内的O-C偶联产物2，该产物具有螺旋骨架，收率很高。可变温度1 H NMR测量表明，化合物2通过热[3.3]σ重排可相互转换，并且[3.3]σ重排的活化自由能随化合物2中亚甲基桥长度的增加而增加。
