New sulfamide compounds and methods of forming those compounds are provided. The inventive methods comprise subjecting a template opened-ring sulfamide compound to a ring-closing metathesis reaction in the presence of a Grubbs catalyst to yield a heterocyclic sulfamide. Advantageously, the template structures can be provided with a wide array of functional groups (e.g., substituted and unsubstituted amino acid side chains, peptides) chosen to provide particular properties to the compound. The preferred heterocyclic sulfamides are represented by a formula selected from the group consisting of

sulfamides and sulfonyl carbamates to generate both symmetric and unsymmetric cyclic sulfamides. Two strategies are revealed, one centers on the RCM reaction of allylated sulfamides 9a–e to generate the C2-symmetric cyclic sulfamides 4a–e in high yields. A second RCM strategy utilizes the known sulfonyl carbamate 15 to prepare unsymmetric cyclic sulfamides 16 and 6 in two four-step sequences. Overall
