Conformational Isomerism of Calixarenes: Isolation of Two Conformational Isomers of the 1,2-Bis(p-tert-butylbenzyl) Ether of p-tert-Butylcalixarene

Article abstract of DOI:10.1021/jo00076a002

Two conformational isomers of the 1,2-bis(p-tert-butylbenzyl) ether of p-tert-butylcalix<6>arene have been isolated by chromatography, and their conformational features have been inferred from NMR spectral evidence, VT-NMR studies, and MM2 molecular mecha
