| Abstract: | Investigation of the colored products formed by the reaction of d-glucose with butylammonium acetate has been extended. The previously unknown 1-N-butyl-4-hydroxy-5-methyl-2-(N-butyl-3-hydroxy-5-(2-hydroxyethyl)pyrrolyl-2-methylidene)-2H-pyrrolin-3-one (2a) was isolated from the reaction mixture and identified after acylation by spectroscopic data. Butylaminammonium acetate was used as a model compound representing the lysine side chains of proteins. |
