carbamate N-alkylation; cesium carbonate
A facile one-pot synthesis of N-alkyl carbarnates is described. A primary amine. CO2, 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 Cs2CO3. subsequent N-alkylation of the in situ generated carbamate with a different alkyl halide afforded various aliphatic N-alkyl carbarnates, respectively.
