first chemo-, regio-, and enantioselective rhodium-catalyzed addition of oximes to allenes is reported. Using a Rh(I)/Josiphos catalyst system under mild conditions, the construction of allylic C–N bonds instead of C–O bonds was achieved. This method permits the atom-economic synthesis of branched allylic nitrones in good to quantitative yields with excellent enantioselectivities.
