The hexaoxa[5.5.5](1,3,5)cyclophane (12) has been synthesised from phloroglucinol and 1,4-dibromobutane by using a stepwise approach. All attempts to effect catalytic hydrogenation of both aromatic rings in the hexaoxa-[6.6.6](1,3,5)cyclophane (12) to give the desired [4]cryptand (14) have proved unsuccessful.
六恶[5.5.5](1,3,5)环烷(12)是由间苯三酚和1,4-二溴丁烷通过逐步方法合成的。已经证明所有尝试对六氧杂环[6.6.6](1,3,5)环烷(12)中的两个芳环进行催化加氢以生成所需的[4] cryptand(14)的尝试均未成功。
