The present invention provides a novel class of macrocyclic compounds, which are useful as cysteine protease inhibitors. Also provided are novel intermediates and methods of preparing the compounds. The invention also provides pharmaceutical compositions comprising the compounds. The compounds and compositions are useful in methods of treating or preventing one or more diseases associated with cysteine protease activity, particularly those associated with calpain activity.

We report the synthesis of macrocycles 1−6 via ringclosingmetathesis of dienes 7−12. Addition of chlorodicyclohexylborane to thermal and microwave assisted RCM of dienes 8 and 9 markedly improves the yield. The geometric isomers of macrocycles 1−3 and 5 have been assigned using X-ray crystallography and NMR.
