  Chiral Microenvironments in Self-Assembled Capsules

  摘要：

  A nonracemic compound is synthesized and shown to assemble reversibly through hydrogen bonding to form a cyclic tetramer. The chiral arrangement of atoms in the individual pieces becomes amplified through self-assembly to yield multiple functional groups asymmetrically arranged within the cavity. The tetrameric capsule shows a special affinity for ketones and is able to discriminate between their enantiomers in solution.

  日期：2001.12.1

  [GRAPHICS]The sulfamide functional group is increasingly relevant in both medicinal and supramolecular chemistry, yet few selective synthetic steps are available for its elaboration. We report here a mild, general, and efficient method for the selective differentiation of N-atom substituents of aromatic sulfamides.
