N-Substituted S-Alkyl Carbamothioates in the Synthesis of Nitrogen-containing Functional Derivatives of the Adamantane Series

A series of new asymmetric ureas, urethanes, and other derivatives of the framework structure have been synthesized by the reactions of adamantan-1-yl isocyanate generated in situ by the thermolysis of carbamothioates with nitrogen-containing nucleophiles and alcohols.

Synthesis and Properties of 1,3-Disubstituted Ureas and Their Isosteric Analogs Containing Polycyclic Fragments: IV.1 1-(Bicyclo[2.2.1]hept-5-en-2-yl)-3-(fluoro, chlorophenyl)ureas

The reaction of bicyclo[2.2.1]hept-5-en-2-yl isocyanate with fluoro- and chloro-substituted anilines was used to synthesize in a yield of 25–68% a series of 1,3-disubstituted ureas containing a lipophilic group in their structure. The synthesized ureas are promising as inhibitors of RNA virus replication and human soluble epoxide hydrolase.
