discusses the synthesis and stereochemical aspects of the anti aldol products, 3-(substituted phenyl)-5-[(substituted phenyl) hydroxy methyl]-5-methyl-4-oxo-2-thioxoimidazolidines. The stereochemistry observed in the aldol reactions with benzaldehydes was explained by transition state model of the endocyclic (E)-enolate formed from the rigid 4-oxo-2-thioxoimidazolidine skeleton. Proton NMR and ROESY spectral
本文讨论了抗羟醛产物3-(取代的苯基)-5-[(取代的苯基)羟甲基] -5-甲基-4-氧代-2-硫氧代咪唑烷类的合成和立体化学方面。由刚性4-氧代-2-硫代氧杂咪唑烷骨架形成的内环(E)-烯醇酸酯的过渡态模型解释了在与苯甲醛的醛醇缩合反应中观察到的立体化学。进行质子NMR和ROESY光谱分析以鉴定醛醇非对映异构体的顺式和反式构象。代表的对映体的配置防通过单晶XRD研究确定醛醇产物3-(4-氯苯基)-5-[(4-氯苯基)羟甲基] -5-甲基-4-氧代-2-硫代氧杂咪唑烷。在体外针对前列腺癌细胞系,PC-3和LNCaP筛选了这些化合物,并确定了最有效的衍生物。
