Intramolecular conversion of N,N-bis(2-picolyl)ureas to cyclic carbamates
2015
Jakob, Uwe | Bannwarth, Willi
Herein, we present a new methodology for preparing 6-membered ring carbamates from a Cuᴵ-promoted cyclization of N,N-bis(2-picolyl)amine substituted ureas. The reactions work best in the presence of up to five-fold excess of CuCl at room temperature in a non-nucleophilic solvent such as acetonitrile. Nine examples of the syntheses are presented to yield products in good to excellent amounts.
