Abstract: A practical method for the synthesis of (S,S)- and (R,R)-1,2-di(furan-2-yl)ethane-1,2-diamine antipodes in a multigram scale is based on the stereoselective reaction of furfural, a biomass processing product, with commercially available enantiomers of 1,2-bis(2-hydroxyphenyl)ethane-1,2-diamine under green chemistry conditions. Simple chemical transformations of the (S,S)-enantiomer were not accompanied by racemization and did not require chromatographic purification of the products. In this way, chiral derivatives of 2,3-diaminosuccinic acid exhibiting antimicrobial properties, and ketopiperazine, a structural fragment of some biologically active compounds, were obtained.

Keywords: biomass conversion, enantioselective synthesis, bioactive compounds, chiral drugs, diaza–Cope rearrangement, 1,2-diamines.
