A High Yielding,One-Pot,Triton-B Catalyzed,Expeditious Synthesis of Carbamate Esters by Four Component Coupling Methodology

摘要

A novel process for the one-step chemoselective conversion of alkyl halides into carba-mates as protected amines was developed using benzyltrimethylammonium hydroxide (Triton-B) in presence of gaseous carbon dioxide.Thus,carbamate esters of different amines were prepared in very good to excellent yields.
