Magnesium triflate was found to effectively catalyze the tert-amino effect reaction (T-reaction) involving ethyl 3-(2-(dialkylamino)-phenyl)-2-nitroacrylates leading to tetrahydroquinoline nitroester derivatives. These compounds can be readily transformed to the corresponding valuable spirohydantoin derivatives.
