Abstract
The selective and symmetrical 1,3,5-methylation of p-tert-butylcalix[6]arene 1 is achieved for the first time; subsequent introduction of ester and amide binding groups on the trimethoxy-p-tert-butylcalix[6]arene 2 fixes the calix in the cone conformation giving new preorganized cation ligands.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
