✦ Synopsis

A facile one-pot synthesis of N-alkyl carbamates is described. A primary amine, CO 2 , and an alkyl halide underwent a three-component coupling using cesium carbonate and tetrabutylammonium iodide (TBAI) giving rise to the resultant carbamate. In the presence of Cs 2 CO 3 , subsequent N-alkylation of the in situ generated carbamate with a different alkyl halide afforded various aliphatic N-alkyl carbamates, respectively.
