The present invention relates to pyrrolidine derivatives and dimeric forms and/or pharmaceutically acceptable esters, and/or salts thereof. The compounds are useful as inhibitors of metalloproteases, e.g. zinc proteases, particularly zinc hydrolases, and which are effective in treating disease states are associated with vasoconstriction of increasing occurrences.
A copper-catalyzedaerobic 3-hydroxyisoindolinone synthesis was developed via the benzylic double C(sp3)–H functionalization of 2-alkylbenzamides. In this reaction, molecular oxygen was used as both an oxidant for C(sp3)–H functionalization and an oxygen source. Our method can be extended to diverse benzylic C(sp3)–H bonds and shows excellent functional group tolerance.

(NHC)-catalyzed benzylic C–H acylation with aldehydes via the hydrogen atomtransfer strategy is disclosed. This transformation involves a sequence of single-electron transfer, 1,5-hydrogenatomtransfer, and radical cross-coupling steps. This method offers facile access to various highly functionalized ketones and exhibits good chemical yields and functional group tolerance.
