Synthesis and crystal structure of a salen-type copper( ii ) complex derived from 3,5′-O-dimethyl-2′,3′-diamino-2′,3′-dideoxy-β- d -xylo-uridine

We report the synthesis of the first 2',3'-diamino substituted uridine derivative with xylo-configuration, its use as starting material for the synthesis of salen-type ligands and the first structurally characterised copper(II) complex thereof.
