The reaction between enamines from β-ketoesters or β-ketonitriles and α-ketoaldehydes was investigated.Besides simple pyrrole and pyrrolinone derivatives, some compounds containing two units of ketoaldehyde were obtained.The structures of the reaction products were established by spectral methods, mainly through the use of two-dimensional NMR techniques and heteronuclear NOE-difference experiments.
