Abstract


It has been found that 4-nitrophenylglyoxal reacts with N-hydroxyurea both in water and in acetic acid forming the mixture of diastereomers of 3,4,5-trihydroxy-5-(4-nitrophenyl)imidazolidin-2-one. The diastereomer with sic-orientation of OH-groups dominates. In the acetic acid medium 4-nitrophenylglyoxal reacts with 2-methylfuran selectively yielding 2-hydroxy-2-(5-methylfuran-2-yl)-1-(4-nitrophenyl)ethanone
