Synthesis of multivalent oxamate ligands based on calix[4]arene and thiacalix[4]arene backbones in 1,3-Alternate conformation

Synthesis of multivalent oxamate ligands based on calix[4]arene and thiacalix[4]arene backbones in 1,3-Alternate conformation
Five new multivalent ligands based on either p-tert-butylthiacalix[4]arene (TCA) 1 or p-tert-butylcalix[4]arene (CA) 2 backbones in 1,3-Alternate conformation bearing four oxamate coordinating groups at their lower rim were designed and synthesized by a multistep strategy. These ligands differ either by the nature of the calix[4]arene backbone (CA or TCA) or by the nature of the spacer ((CH2)n) connecting the oxamate binding units to the backbone.
