Nine pyrimidine nucleoside analogues, in which the group attached at N-1 is a six-membered ring containing two heteroatoms, have been synthesized using the Vorbrüggen and Bennua (Vorbrüggen, H.; Bennua, B. Tetrahedron Lett. 1978, 1339) coupling procedure. These are 1-(1,4-oxathian-3-yl)-5-fluorouracil (8), 1-(4-oxo-1,4-oxathian-3-yl)-5-fluorouracil (two stereoisomers 9 and 10, resolved by silica gel
已使用Vorbrüggen和Bennua(Vorbrüggen,H .; Bennua,B.Tetrahedron Lett。1978,1339)偶联合成了九个嘧啶核苷类似物,其中在N-1处连接的基团为包含两个杂原子的六元环。程序。它们是1-(1,4-氧杂蒽-3-基)-5-氟尿嘧啶(8),1-(4-氧杂-1,4-氧杂蒽-3-基)-5-氟尿嘧啶(两个立体异构体9和10 ,通过硅胶柱色谱分离,1-(1,4-氧杂蒽-3-基)-5-氟尿嘧啶(11),1-(1,4-氧杂蒽-2-基)-5-氟尿嘧啶(12), 1-(1,4-二硫-2-基)-5-氟尿嘧啶(15),1-(1,4-二硫-2-基)尿嘧啶(16),1-(1,4-二硫-2-基) yl)胸腺嘧啶(17)和1-(1,4-dioxan-2-yl)-5-氟尿嘧啶(20)使用小鼠和人类肿瘤细胞系测试了所有类似物对细胞生长的抑制作用。所有类似物的值均大于10(
