Thomas Nugent and colleagues at Jacobs University describe the use of a three component catalyst, an amino acid, a base and a hydrogen bond donor, to form quaternary C-C bonds in this paper that is the front cover of 
The very successful OBC Communication by Robert H. Cichewicz and coworkers, at the University of Oklahoma, on mutanobactin A and its influence on the yeast-mycelium transition of Candida albicans is now the inside cover of Issue 24.
Rajeev Menon and Martin Banwell at the Australian National University in Camberra have identified a novel and highly efficient Au (I) catalysed intramolecular Michael addition reaction that is a key step towards the first total synthesis of crassifolone and dihydrocrassifolone.
