The sulfamide functional group has been extensively employed in organic synthesis to discover probes and drugs in various applications such as cancer, human immunodeficiency virus (HIV), virus, and diabetes. Herein, we describe the synthesis of 7-membered symmetric and unsymmetric sulfamide compounds and their biological evaluation through the National Cancer Institute (NCI) panel of 60 human tumor

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

approach that incorporates structural requirements for the formation of a 1D assembly, fibril stability, and fibril–fibril interactions for gelation was attempted by using amino acid‐based sulfamides with the general structure Aa‐NH‐SO2‐NH‐Aa (Aa=amino acid). A preference for 1D assembly alone was not a sufficient condition for gelation, which became evident from studies involving sulfamide esters 1–5. Reducing

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
GRAPHICAL ABSTRACT ABSTRACT An improved environmentally benign method for synthesis of sulfamides under focused ultrasound irradiation and under solvent-free and catalyst-free conditions has been carried out by the reaction of amines or amino esters with sulfuryl chloride. This approach allows the synthesis of products in excellent yields and in short reaction time.
