摘要：

In competitive complexation of Z-amino acids (N-benzyloxycarbonyl-amino acids) in CDCl3, a synthetic receptor such as zinc N-methylmesoporphyrin II having a xylylenediamido strap (1a) preferred Z-glycine over other Z-amino acids, where an excellent selectivity (> 90 %) was achieved when Z-beta-alanine, Z-sarcosine, Z-leucine, or Z-proline was the competitor. In contrast, in competitive binding of Z-amino acid anions in a CHCl3/water biphasic system, 1a preferred substrates with hydrophobic side chains. (C) 1997 Elsevier Science Ltd.
