The preparation of hitherto unknown, 2′,3′-didehydro-3′-deoxythymidine derived 5′-thioether, sulfoxide, sulfone [4–9] is described. The key steps of this synthesis are the nucleophilic displacements of a halogen by a thioalkyl sodium salt, and the later oxidation of the sulfur group into sulfone and sulfoxide analogues. These compounds have been evaluated for their inhibition of L1210 cells proliferation
描述了迄今未知的2',3'-didehydro-3'-deoxythymidine衍生的5'-硫醚,亚砜,砜的制备方法[ 4-9 ]。该合成的关键步骤是通过硫代烷基钠盐进行卤素的亲核取代,以及随后将硫基氧化为砜和亚砜类似物。已评估这些化合物对L1210细胞增殖的抑制作用。除了显示中等活性(IC 50为90.2μM)的5'-乙硫基类似物4b外,所有化合物均无活性。©1997爱思唯尔科学有限公司。
