Synthesis of a new cylindrical calix[4]arene-calix[4]pyrrole pseudo dimer
Synthesis of a new cylindrical calix[4]arene-calix[4]pyrrole pseudo dimer
The synthesis of a new calixarene-capped calixpyrrole 2 has been achieved using p-tert-butylcalix[4]arene tetramethyl ketone 1 as a template. Using this approach, the stereochemistry at the calixpyrrole meso-carbons is automatically defined. The X-ray crystal structure of 2 has been elucidated and reveals hydrogen bonding between the pyrrole NH groups and the oxygens at the lower rim of the calixarene. NMR studies confirm the importance of these interactions in solution.

Abstract
The synthesis of a new calixarene-capped calixpyrrole 2 has been achieved using p-tert-butylcalix[4]arene tetramethyl ketone 1 as a template. Using this approach, the stereochemistry at the calixpyrrole meso-carbons is automatically defined. The X-ray crystal structure of 2 has been elucidated and reveals hydrogen bonding between the pyrrole NH groups and the oxygens at the lower rim of the calixarene. NMR studies confirm the importance of these interactions in solution.
