A xanthate-based oxidative radical process for the directalkylation of the coumarin ring system is presented. In the reaction, a vinylic and unactivated C–H bond of the coumarin system is replaced by an α-acyl functionality under neutral conditions. This reaction has a high reaction site selectivity, which can realize alkylation at the C-3 position.

This invention relates to new inhibitors of chymothrypsin-like activity of the immunoproteasome (inhibitors of β5ί or LMP7 subunit) with the general formula (I), where substituents are described in patent description. Compounds can be in the form of pure enantiomers or as racemic mixtures, or in the form of pharmaceutically acceptable salts. The present invention relates to the use of these inhibitors for the treatment of diseases where immunoproteasome activity is increased.
