The scope and limitations of the direct organocatalytic asymmetric α-aminomethylation of ketones are disclosed. The proline-catalyzed classical Mannich reactions between unmodified ketones, aqueous formaldehyde and aromatic amines furnished the desired Mannich bases in high yield with up to >99% ee. Moreover, methyl alkyl ketones were regioselectively α-aminomethylated at the methylene carbon affording

This invention relates to compounds useful as lysyl oxidase (LOX) and lysyl oxidase-like (LOXL) family member (LOXL1, LOXL2, LOXL3, LOXL4) inhibitors. In addition there are contemplated pharmaceutical compositions comprising the compounds and the use of the compounds in the treatment of conditions mediated by LOX and LOXL, for example cancer. In particular a LOX inhibitor such as the present compounds may be for use in the treatment of a cancer associated with EGFR. The present invention also contemplates the identification of biomarkers that predict responsiveness to a LOX inhibitor.
