A coumpound of the formula (I) wherein each X is independently NR1R6, NR4R5, or R4, with the proviso that at least one X must be NR1R6; each R1 is independently an optionally substituted fused bicyclic unsaturated ring containing 9 or 10 atoms optionally containing 1-4 heteroatoms selected from the group consisting of N, S and O, and the variables R2-6 are as defined in claim 1, are claimed. These compounds are kinase inhibitors useful in the treatment of cancer and viral infections.

[reaction: see text] The rhodium(I)-catalyzed methylenation of functionalized fluorinated ketones using trimethylsilyldiazomethane proceeds to give the corresponding fluoromethylalkenes in good yields (61-90%). Remarkable chemoselectivity was observed for the synthesis of keto-substituted organofluorine alkenes.
