Easily Separable Racemic and Meso Isomers of a Salen-Based Cryptophane for Selective Guest Binding
A salen-based cryptophane cage was synthesized via dynamic covalent imine chemistry, affording separable meso and racemic isomers. Single-crystal X-ray analysis confirmed the structure of the racemic form. The isomers exhibited slow interconversion in solution, enabling an individual study of their properties. The racemic isomer bound quaternary ammonium guests with notable size selectivity, highlighting the potential of imine-based cryptophanes as functional hosts for molecular recognition.
期刊介绍:
Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
