A novel and efficient synthesis of N-substituted pyrrolo-pyrazinone derivatives has been developed. A trichloroacetyl group connected to the pyrrole ring was converted into the desired carboxamide derivatives. Promoted by NaH, the pyrrole carboxamide derivatives underwent a tandem reaction with propargyl bromide to afford pyrrolo-pyrazinones with high efficiency under very mild conditions. The mechanism for the formation of the products is discussed and supported by DFT calculations. (C) 2014 Elsevier Ltd. All rights reserved.

A transition metal-free tandem process for the synthesis of pyrrolopyrazino[2,3-d]pyridazine-diones is described. The process is an efficient construction of this tricyclic system by a one-pot coupling/Smiles rearrangement/cyclization approach. This methodology has potential applications in the synthesis of biologically and medicinally relevant compounds. (C) 2011 Elsevier Ltd. All rights reserved.
