The synthesis of 7-membered cyclic sulfamides utilizing the RCM reaction is described herein. Two major synthetic strategies that expand the scope and utility of our previously reported sulfamide and sulfamoyl carbamate chemistry are employed. Both Mitsunobu alkylation and simple alkylation of core sulfamides and sulfamoyl carbamates coupled with RCM are used to efficiently install lipophilic groups
