A catalyst generated in situ from [Rh(COD)Cl]2, (R)-DTBM-SEGPHOS, and NaBARF promotes an endo- and enantioselective hydroacylation of ortho-allylbenzaldehydes. These rhodium-catalyzed processes generate the 3,4-dihydronaphthalen-1(2H)-one products in good yields with excellent enantioselectivities with minimal formation of byproducts from competitive alkene isomerization and ene/dehydration pathways.
