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