Synthesis and structure of the copper(II) complex of a chiral bis(dihydrooxazole) ligand

The bridged bis(dihydrooxazole) compound (−)-2 and its silylated derivative (−)-3 have been synthesised as building blocks for chiral ligands. The complex of (−)-3 with Cu II has been obtained, and its crystal structure has been determined. The Cu II ion is bound to two deprotonated ligands in a twisted tetracoordinated geometry
