A series of chiral C2-symmetric bis(oxazoline) ligands containing semicrown ether unit were synthesized. The copper complexes prepared in situ from copper(I)-triflate, and the new chiral oxazoline ligands were assessed as chiral catalysts in th

The macrocyclic diamides 11-21, 42 and 43 were prepared by nucleophilic reaction of the bis phenols 22-29 with the appropriate dihalo compounds 2, 3, 40 and 41, respectively. The macrocyclic dithiodiamides 30-33 were obtained in good yields upon treatment
