Cover Picture
Olga Iranzo, Chris Cabello, and Vincent L. Pecoraro*
Heterochromia is a genetic condition that causes individuals to have eyes of different
colors. In the same way, nearly identical metal-binding sites in heterochromic
peptides, an example of which is presented by V. L. Pecoraro and co-workers in their
Communication on page 6688 ff., display different physical properties after metal
binding. The cover picture shows a de novo designed heterochromic peptide that
binds two CdII ions, each with a different coordination geometry.
Natural Product Synthesis
In their Minireview on page 6586 ff., M. K&ck, P. S. Baran, and co-workers trace
how the structure of palau)amine came to be reassigned and describe the
implications for the biosynthesis and total synthesis of marine natural products.
Arenes with Group 14 Elements
A. Sekiguchi and V. Ya. Lee summarize in their Review on page 6596 ff. the current
state of affairs in the field of aromatic compounds with Si, Ge, Sn, and Pb atoms and
address factors influencing their degree of aromaticity.
Actinide Complexes
A cis-dioxido uranium(VI) complex, described by P. B. Duval et al. in their
Communication on page 6622 ff., exhibits an unprecedented geometry which
probably results from steric pressure in a fluxional process that involves a concerted
carboxylate-ligand activation.
