Cover Picture: Regioselective Organocatalytic Formation of Carbamates from Substituted Cyclic Carbonates (Adv. Synth. Catal. 13/2016)

The inside cover picture , provided by Arjan W. Kleij and co‐workers, illustrates an example of regio‐directing : a general route towards the regio‐selective formation of carbamates derived from substituted cyclic organic carbonates and amines is reported using a readily available organocatalyst (TBD; 1,5,7‐triazabicyclo[4.4.0]dec‐5‐ene) under attractively mild reaction conditions. The carbonate substitution pattern and the presence of a ternary intermediate dictate the carbonate bond scission process giving preferentially rise to highly functional carbamates with tertiary alcohol functions. The easy and regio‐selective formation of di‐carbamates/urethanes shows the potential of this process to become valuable in the context of the preparation of regio‐regular oligo/polyurethanes.
