Cover Picture Chandrakala Pidathala, Linh Hoang, Nicola Vignola, and Benjamin List* A feather in the cap of the aldol reaction. The cover picture shows the amino acid (S)-proline surrounded by some new catalytic asymmetric intramolecular aldolizations, which are described by B. List et al. on page 2785 ff. Another example of the ever-increasing number of proline-catalyzed reactions are enolexo aldolizations. Despite these exciting discoveries, it is often forgotten that almost half of the 250 tonnes of proline produced each year is isolated from chicken feathers!
