Nickel‐Catalyzed Tandem Ring Contraction of TEMPO and C‐N Bond Transamination of Enaminones toward Amino Diversity of Enaminones


The reactions of N,N -substituted enaminones with TEMPO top to the synthesis of 2,2-dimethyl pyrrolidine functionalized new enaminones have been set up by Ni(II) catalysis. Interesting ring contraction on TEMPO as effectively as the enaminone C-N bond amination deliver new device for generating molecular range of enaminones in the amino team fragment.
