✦ Synopsis

Application in veterinary medicine was proposed for the sesquiterpenoids pasteurestins A and B because of their strong and selective activity against Pasteurella haemolytica. A Vollhardt [2þ2þ2] cycloaddition was the key step in their total synthesis, which is described by J. Mulzer et al. on page 9320 ff., and subsequently their absolute and relative configurations could be established and their biological activities more precisely specified. Another feature of the synthesis of pasteurestin B is a tin(II) enolate mediated Reformatsky-type condensation.

**Rodlike nanocrystals** typically pack in a parallel fashion as dictated by their anisometric shape and stiffness. In their Communication on page 2195 ff., E. R. Zubarev and B. P. Khanal report the spontaneous self‐organization of polymer‐coated metallic nanorods into circular arrays (see picture).
