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.
