Macrocyclic cis- and trans-bis(alpha-amino acids) and their intraannular Cu(II) complexes. Conformational in-out dichotomy and crystal packing

Abstract

Macrocyclic bis(alpha-amino acids) cis- and trans-2a-b were prepared from the selectively protected tris(hydroxymethyl)aminomethane 3. The X-ray structures of the free bis(amino acids) and/or of the corresponding Cu(II) complexes
