The present invention relates to tricyclic compounds of formula (I) or pharmaceutically acceptable salt thereof as mPGES-1 inhibitors. These compounds are inhibitors of the microsomal prostaglandin E synthase-1 (mPGES-1) enzyme and are therefore useful in the treatment of pain and/or inflammation from a variety of diseases or conditions, such as asthma, osteoarthritis, rheumatoid arthritis, acute or chronic pain and neurodegenerative diseases.

A new approach to hetaryl carbamates through a tandem condensation/rearrangement reaction of 2‐aminohetarene N‐oxides was developed. The developed reaction is suitable for both five‐ and six‐membered heterocycles and proceeds through the condensation of 2‐aminohetarene N‐oxide with trimethyl orthoformate followed by intramolecular N‐oxide oxygen transfer. For five‐membered hetarene N‐oxides (furoxans)

A straightforward method for the facile access of isoindolone spirosuccinimides has been developed through N,O-directing group-assisted, cobalt-catalyzed C−H functionalization of benzamides. Co-catalyzed C−H bond activation is the rate-determining step of this reaction.
