α, β, γ: The title method employs a Mg/L catalyst, which is well suited for the selective γ deprotonation and activation of linearα,β‐unsaturated ketones for reaction with nitroalkenes. The reaction leads to a series of optically active cyclohexene ring systems bearing multiple functional groups, systems which are not easily accessible using other methodologies.
