We investigated the selective formation of homoleptic and heteroleptic metal complexes controlled by means of the chiral molecular instruction of the ligand and the coordination geometry of the metal. Our results showed that chiral self-recognition or self-discrimination may be induced by the CuI/CuII redox transition using cyclic voltammetry. The further use of chiral ditopic ligands led to metallo-supramolecular copolymers with stimuli-responsive controlled arrangement.

Multitopic chiral copper complexes based on bis(oxazoline) have been applied in the enantioselective α-hydrazination of β-ketoesters. High yields and excellent enantioselectivities were obtained. Furthermore, the catalytic systems have been recovered in u

The first example of catalytic asymmetric [1,2]-Stevens rearrangement reaction of 1,3-oxathiolanes with diazomalonates has been developed and up to 90% ee is achieved by the bisoxazoline 4e/ copper(II) triflate [Cu(OTf) 2] complex.
