Organic carbamates represent an important class of compounds showing various interesting properties. They find wide utility in various areas as pharmaceuticals, agrochemicals (pesticides, herbicides, insecticides, fungicides etc.), intermediates in organic synthesis, protection of amino group in peptide chemistry, and as linker in combinatorial chemistry etc. Classical synthesis of carbamates involves use of harmful reagents such as phosgene, its derivatives and carbon monoxide. Recently, various kinds of synthetic methods have been developed for the synthesis of organic carbamates. In the present review, I would like to highlight the recent developments on the synthesis of organic carbamates using variety of reagents.
