The Knoevenagel condensation product of pyridoxal 5′-phosphate (1) with rhodanine (2) was prepared and identified as (Z)-5-[[3-hydroxy-2-methyl-5-[(phosphonooxy)methyl]-4-pyridinyl]methylene]-2-thioxo-4-thiazolidinone (3). The labile (E)-stereoisomer 4 was obtained in a crude form. Its association with the nucleobase adenine was prepared suggesting an affinity to nucleic acids.
制备了吡ido醛5'-磷酸(1)与若丹宁(2)的Knoevenagel缩合产物,并将其鉴定为(Z)-5-[[3-羟基-2-甲基-5-[(膦酰氧基)甲基] -4-吡啶基]亚甲基] -2-硫代氧-4-噻唑烷酮(3)。以粗制形式获得不稳定的(E)-立体异构体4。制备了其与核碱基腺嘌呤的缔合,表明对核酸具有亲和力。
