Hofmann, Thomas published the artcileIdentification of Novel Colored Compounds Containing Pyrrole and Pyrrolinone Structures Formed by Maillard Reactions of Pentoses and Primary Amino Acids, Recommanded Product: Ethyl 2-Iodopropionate, the publication is Journal of Agricultural and Food Chemistry (1998), 46(10), 3902-3911, database is CAplus.

Heating of pentoses with alanine in a ratio of 10:1 in aqueous solution at pH 7.0 generated the yellow 2-[(2-furyl)methylidene]-4-hydroxy-5-methyl-2H-furan-3-one, being well in line with data reported in the literature. Decreasing the relative concentrations of the pentose produced further colored nitrogen-containing compounds, among which (S)-4-hydroxy-5-methyl-2-[N-(1′-carboxyethyl)pyrrolyl-2-methylidene]-2H-furan-3-one could be identified by spectroscopic and synthetic experiments On the other hand, thermal treatment of an aqueous solution of pentose and L-alanine in the presence of furan-2-carboxaldehyde led to the formation of the novel red (2R)-4-oxo-3,5-bis[(2-furyl)methylidene]tetrahydropyrrolo[1,2-c]-5(S)-(2-furyl)oxazolidine and its 5(R)-(2-furyl)oxazolidine diastereomer, which were characterized by several 1D- and 2D-NMR techniques, LC/MS, and UV-vis spectroscopy as well as by synthesis of the chromophoric substructure. In addition, the red compounds (S)-4-[(E)-1-formyl-2-(2-furyl)ethenyl]-5-(2-furyl)-2-[(E)-(2-furyl)methylidene]-2,3-dihydro-α-amino-3-oxo-1H-pyrrole-1-acetic acid and the corresponding 2-[(Z)-(2-furyl)methylidene] isomer were identified in this Maillard mixture Quant. studies on the formation of these colorants clearly demonstrates the key role of 3-deoxypentos-2-ulose as an intermediate. Reaction pathways leading to the colorants from pentoses and alanine are discussed.
