Cover Feature: Lewis Base Catalysis Promoted Nucleophilic Substitutions – Recent Advances and Future Directions (Eur. J. Org. Chem. 1/2020)

The Cover Feature shows Lewis base catalyzed nucleophilic substitutions (SN) engaging non‐activated alcohols, carboxylic acids, aldehydes, and epoxides as substrates. In fact, SN‐transformations are of fundamental significance in chemistry. Especially in the last decade, powerful catalytic approaches for SN‐type C–C, C–N, C–O, and C–Cl bond formations have been implemented. The current review outlines modern concepts for catalytic SN‐conversions and details novel Lewis base promoted methods. More information can be found in the Minireview by P. H. Huy et al.
