The present invention relates to compounds that inhibit of focal adhesion kinase function, processes for their preparation, pharmaceutical compositions containing them as the active ingredient, to their use as medicaments and to their use in the manufacture of medicaments for use in the treatment in warm-blooded animals such as humans of diseases such as cancer.
synthetic equivalent of α-hydroxy and α-chloro benzyl carbanions by means of a two-step sequence involving (1) highly stereoselective α-C-alkylation with alkyl bromides, and (2) displacement of the sulfinylgroup by an OH or a Cl underPummerer or chloro-Pummerer conditions, respectively. The sulfinyl auxiliary can be effectively regenerated and recycled.

The present disclosure provides novel POZ-2 derivatives, methods for synthesizing POZ-2 derivatives and intermediates useful in such methods. In one embodiment, the POZ-2 derivative comprises two linear POZ chains of the present disclosure linked directly or indirectly to a branching moiety that contains a functional group for linking the POZ-2 derivative to the target molecule. Target molecule-POZ-2 conjugates are also described. In certain embodiment, the POZ-2 derivatives have low polydispersity values and a decreased amount of impurities produced by unwanted side reactions, such as, but not limited to, chain transfer.
