Abstract
Abstract The reaction of ethyl 2-(N,N-dimethylamino)penta-2,4-dienoate 4 with acrylonitrile 2 gave the methyl N-methyl-2-(2-propenyl)-3-cyano-pyrrolidine-2-carboxylate 5a and 5b as a [3 + 2]-atoms “cycloadducts”. The putative [1,3] dipolar intermediate species azomethine ylide 4c , results from [1,6] hydrogen shift of one N(CH3) proton.
