| Abstract |
The tetramethyl (2) and tetraethyl (3) ethers, and the tetraacetate (4) derivatives of the p-tert butyldihomooxacalix[4]arene were prepared. The mobility of these compounds studied by temperature-dependent H-1 NMR spectroscopy. For the tetraacetate derivative, at room temperature, 1,2- or 1,3-alternate conformations are suggested. Those conformations were confirmed by NOE difference and COSY spectra for the tetraethyl ether derivative in CDCl3 at -20 degrees C. |
