Cyclic sulfates and sulfamidates are precursors for the synthesis of alkyl chains bearing sulfur, nitrogen and oxygen functionalities. Medicinal chemists often use them as alkylating reagents. A wide variety of chemically and biologically important molecules have been prepared from cyclic sulfates and cyclic sulfamidates. Herein, we have designed and synthesized a library of cyclic sulfates and sulfamidates for medicinal chemistry projects.
