The present invention provides oxalic amide ligands and uses thereof in copper-catalyzed coupling reaction of aryl halides. Specifically, the present invention provides a use of a compound represented by formula I, wherein definitions of each group are described in the specification. The compound represented by formula I can be used as a ligand in copper-catalyzed coupling reaction of aryl halides for the formation of C—N, C—O and C—S bonds.
The invention provides a compound which is an iV-oxalylglycine derivative of formula (I): a hydroxamic acid derivative of formula (II): or a heteroaryl derivative of fomula (III): wherein n; Z1; Z2; Y1; Y2; A; p; X1; X2; m; R4; B; R5; R6; R7; R8; R9; X3; R10; R11 and R12 are as defined herein, or a pharmaceutically acceptable salt thereof. These compounds are inhibitors of the human 2-oxoglutarate-dependant JMJD2 subfamily of histone demethylases, in particular JMJD2E. Such inhibitors are useful in changing the epigenetic state of cells resulting in the inhibition / activation of chromatin remodelling, multiple gene activation / deactivation, and in treating cancer and other conditions characterised by undesirable cellular proliferation, and psychiatric disorders including depression.

modular ligand library, high-throughput experimentation, and rational ligand evolution have led to a novel copper catalyst for the synthesis of phenols with a traceless hydroxide surrogate. The mild reaction conditions reported here enable the late-stage synthesis of numerous complex, druglike phenols.
