Back Cover: Recyclable Poly‐Zn 3 (OAc) 4 –3,3′‐Bis(aminoimino)binaphthoxide Catalyst for Asymmetric Iodolactonization (ChemCatChem 20/2015)

The Cover shows an image of a polymer catalyst for iodolactonization (two kinds of “gingerbread men” represent the spacers 3,3’‐diformyl binaphthol and the tetramine). In their Communication, T. Arai et al. reported a Zn 3 (OAc) 4 ‐3,3’‐bis(aminoimino)binaphthoxide (tri‐Zn) catalyst for the asymmetric iodolactonization. Based on the structure of unimolecular tri‐Zn catalyst, a poly‐Zn complex was also prepared by the self‐organization of 3,3’‐diformyl binaphthol, tetramine, and Zn(OAc) 2 . More details can be found in the Communication by T. Arai et al. on page 3234 in Issue 20, 2015 (DOI: 10.1002/cctc.201500842).
