A Michael addition/iminium ion cyclization cascade of enones with tryptamine-derived ureas under BINOL phosphoric acid (BPA) catalysis Is reported. The cascade reaction tolerates a wide variety of easily synthesized tryptamine-derived ureas, including those bearing substituents on the distal nitrogen atom of the urea moiety, affording polyheterocyclic products in good yields and good to excellent enantioselectivities.

The present invention refers to novel substituted aromatic heteroaryl derivatives of formula (I), with the definitions of a, L1, L2, G, J, X and Y according to claim 1. These novel compounds are useful for the inhibition of protein kinases, particularly of the inhibition of Src family protein kinases. Methods for inhibiting kinases by contacting kinases with these novel compounds are disclosed. In another embodiment the present invention refers to pharmaceutical compositions containing these novel compounds and their use of medicaments for treating diseases or disorders associated with unphysiological activity of kinases in the body, particularly for the treatment of cancer, immunosuppression, and osteoporosis.
