The cover picture shows the general structure of the first easily recoverable and reusable molecular chiral thioureas to be used as organocatalysts in asymmetric nitro‐Michael reactions. They were prepared by functionalization of amines obtained from [60]fullerene and aldehydes. The recovery of the catalysts is based on the low solubility of fullerene derivatives in different organic solvents, and they can be used at 0.5 mol‐% loading. The artwork is by P. Higuero and represents the easy recoverability of the catalysts after the goal of the catalytic process. Details are discussed in the Full Paper by R. Pedrosa et al. on page 2683 ff (DOI: 10.1002/ejoc.201601640 ).
