Synthesis of Bicyclic Isocyanates and Bioisosteric 1,3-Disubstituted Ureas as Soluble Epoxide Hydrolase Inhibitors

详细

(1S)-1-Isocyanato-4,7,7-trimethyl-2-oxabicyclo[2.2.1]heptan-3-one and 2-isocyanatobicyclo[2.2.1]-hept-5-ene were prepared by the Curtius rearragement reaction from the corresponding carboxylic acids. The synthesized isocyanates were used to synthesize, in high yields of 74–93%, bioisosteric 1,3-disubstituted ureas as potential human soluble epoxide hydrolase inhibitors.
