A new strategy for the synthesis of 3-methylene-2,3-dihydro-1 H -pyrazoles is presented by Ni-catalyzed oxidative cyclotrimerization of α-aminoketones. This unprecedented method allows three α-aminoketones to undergo sequential multiple deprotonations and deamination through two C–C bonds and one N–N bond formation cascade.
