Macrocyclic receptor 1 has been synthesised, as a racemate and as a single enantiomer, utilising a Stille coupling for the formation of the biphenyl portion and a macrolactamisation as the final step. The binding properties for the racemic and the homochiral macrocycle with amino acid and dipeptide
