  Acidified Alcohols as Agents to Introduce and Exchange Alkoxyls on the Periphery of Helicenes

  摘要：

  Alcohols containing HCl transform the hydroquinone reduction-products of helicenebisquinones into p-alkoxyphenols that have the alkoxyls specifically on the peripheries of the helices. The reactions are quick, and the yields are high. Alkoxyls at the 6-position are replaced also, but only after 2 h at 60 degrees C, not after the 5 min at 25 degrees C sufficient to replace the peripheral hydroxyls of the hydroquinones. After the remaining inside hydroxyls of a dihydroxytetramethoxy[6]helicene prepared by this procedure have been converted into camphanates, one diastereomer crystallizes from solution, allowing an enantiomer resolution to be carried out on a large scale. By then simply reapplying the procedure with alcoholic acid, a variety of resolved dihydroxytetraalkoxy[6]helicenes can be prepared in excellent yields without resolution procedures having to be developed for each, Similar procedures are effective when applied to a [7]carbohelicene.

  功能化螺旋的有效合成

  摘要：

  [5]-和[6]螺旋烯双醌可以通过将1,4-二乙酰苯或2,7-二乙酰萘的烯醇醚与对苯醌组合而容易且大量制备。类似的二乙烯基芳烃要么没有醚官能团，要么没有连接到双键上，而是连接到芳环上，只能以低产率和低纯度得到相应的螺旋。[6] Helicenebisquinone 11c 被拆分成它的对映异构体。这些对映异构体之一和 l-脯氨醇的加合物的 X 射线衍射分析显示了 11c 的绝对立体化学和胺与醌加成的区域化学。
