Aj. Kesel et al., INTERCONVERTIBLE (Z E)-STEREOISOMERS OF A VITAMIN-B-6 COENZYME ANALOGDERIVED FROM PYRIDOXAL 5'-PHOSPHATE AND RHODANINE/, Tetrahedron, 52(47), 1996, pp. 14787-14800
The Knoevenagel condensation product of pyridoxal 5'-phosphate (1) wit
h rhodanine (2) was prepared and identified as oxy-2-methyl-5-[(phosph
onooxy)methyl]-4-pyridinyl] methylene]-2-thioxo-4-thiazolidinone (3).
The labile (E)-stereoisomer 4 was obtained in a crude form. Its associ
ation with the nucleobase adenine was prepared suggesting an affinity
to nucleic acids. Copyright (C) 1996 Elsevier Science Ltd
