Synthesis and Properties of 1,3-Disubstituted Ureas and Their Isosteric Analogs Containing Polycyclic Fragments: V. 1-(Bicyclo[2.2.1]heptan-2-yl)-3-R- and 1-(1,7,7-Tricyclo[2.2.1]heptan-2-yl)-3-R-ureas

Abstract

Abstract: A series of 1,3-disubstituted ureas containing a bicyclic lipophilic group ofnatural origin were synthesized by the reactions of bicyclo[2.2.1]heptane-2-ylisocyanate with amines in yields of up to 82% and by the reactions ofbicyclo[2.2.1]heptan-2-amine and 1,7,7-trimethylbicyclo[2.2.1]heptan-2-aminewith 1,1'-carbonyldiimidazole in yields of up to 94%. The synthesized ureas arepotent inhibitors of RNA virus replication and soluble epoxide hydrolase.
