We describe an efficient method for the synthesis of aminocyclobutanes via a [2 + 2] cycloaddition between a keteniminium salt and an alkene, followed by a reduction step. The use of easily removable N-allyl moieties as protecting groups increases the potential of this method to access, in a few steps, highly functionalized cyclobutaneamine-containing building blocks. Moreover, DFT calculations verify
