The Cu(acac)2 catalyzed reactions of dimethyldiazomalonate with enaminones yielded 1,5-cyclization and α-CH insertion products. In the case of anilino derivatives (R1 or R2 = Ph), products resulting from an unusual insertion to the benzoyl ring dominated the reaction.

An efficient cascade β-metalation/addition/cyclizationreaction promoted by LDA is described in which 3-amino furans were constructed from enaminones and aldehydes. A broad range of substituents on the starting compounds was tolerated, and the polysubstituted furans were gained with moderate to excellent yields within 2 h.

Organic metathesis reactions allow for expedient assembly of diverse molecular skeletons and appendages through the exchange of molecular fragments. The olefin–imine variant of this process, in particular, can expand the synthetic toolbox for manipulating carbon–carbon and carbon–nitrogen bonds but has thus far been achieved only on a stoichiometric metal-mediated basis. Herein, we report the development
