CHEMISTRY: Anion Induction

Anion transport and supramolecular medicinal chemistry.

New approaches to the transmembrane transport of anions are discussed in this review. Advances in the design of small molecule anion carriers are reviewed in addition to advances in the design of synthetic anion channels. The application of anion transporters to the potential future treatment of disease is discussed in the context of recent findings on the selectivity of anion transporters.

Anion receptor chemistry: highlights from 2011 and 2012.

This review covers advances in anion complexation in the years 2011 and 2012. The review covers both organic and inorganic systems and also highlights the applications to which anion receptors can be applied such as self-assembly and molecular architecture, sensing, catalysis and anion transport.

Anion channel involved in induction of apoptosis and necrosis.

Total Synthesis of (−)-Secu’amamine A Exploiting Type II Anion Relay Chemistry

A total synthesis of (-)-secu'amamine A has been achieved exploiting Type II Anion Relay Chemistry (ARC) to provide the full linear carbon and nitrogen skeleton in a single flask with the requisite stereochemistry and functionality. A mechanistic rationale is also proposed to account for the stereochemical outcome of the key aldol reaction leading to the advanced aza tricyclic core.

The Saccharinate Anion: a Versatile and Fascinating Ligand in Coordination Chemistry

Saccharin (o-sulfobenzimide; 1,2-benzothiazole-3(2H)-one 1,1 dioxide; Hsac, Figure 1) is one of the best known and most widely used artificial sweetening agents. Initially, investigation of the interaction of saccharin with different biologically relevant cations attracted great interest due to the suspected carcinogenicity of this compound which, notwithstanding, was recently definitively rule...
