Abstract

The reactions of (S)-3-cyanophenylalanine with NaN(3) in the presence of H(2)O and Lewis acids (ZnCl(2) and CdCl(2)) afford two unprecedented 3D homochiral networks, mono[(S)-5-(3-tetrazoyl)-phenylalaninato]zinc(II) (1) and mono[(S)-5-(3-tetrazoyl)-phenylalaninato]cadmium(II) monoaqua(II) (2), respectively. The two compounds are isostructural with noninterpenetrated SrAl(2) topology. The structure of these coordination polymers gives new insight into Sharpless' reaction of chiral 5-substituted 1H-tetrazole and homochiral supramolecular array constructions.

摘要

在水和路易斯酸（氯化锌和氯化镉）存在的情况下，（S）-3-氰基苯丙氨酸与叠氮化钠反应分别生成两个前所未有的三维同手性网络，即单[（S）-5-（3-四唑基）-苯丙氨酸根]锌（II）（1）和单[（S）-5-（3-四唑基）-苯丙氨酸根]镉（II）一水合物（2）。这两种化合物具有非穿插的SrAl₂拓扑结构的同构结构。这些配位聚合物的结构为手性5-取代-1H-四唑的夏普莱斯反应和同手性超分子阵列构建提供了新的见解。
