Abstract
A new approach to cap 1,3,5-trimethyloxy- p- tert-butyl calix[6]arene with 1,1,1-tri(tosyloxyethoxyethoxymethyl)propane to form a pair of separable stabilized in- and out- calix[6]cryptands was reported. After heating 5a or 5b at 280°C, the interconversion between them was not detected by TLC, which provides a direct and non-spectral methodology to obtain unambiguous evidence for the ring immobilization in calix[6]arenes with stereoisomers.
