A highly regio‐, diastereo‐ and enantioselective addition of 2‐acylimidazoles or 2‐acyl pyridines with allenes promoted by Rh/Lewis acid synergistically catalytic system is described. This atom economic approach leads to the formation of the branched allylic alkylated products including acyclic quaternary all‐carbon stereogenic centres in good yields with good to excellent diastereo‐ and enantioselectivities
Imidazo[1,2-a]pyridines are disclosed. Compounds of the invention are useful therapeutic agents and their inclusion in pharmaceutical formulations and use in methods of treatment are disclosed.
