have been achieved via treatment of the corresponding 3′,5′-oxetane with sodium hydroxide in hexamethylphosphoric triamide. The 2′,3′-unsaturated nucleosides ( 5a and 5b ) were converted into 1-(5-amino-2,3,5-trideoxy-β- d - glycero -pent-2-enofuranosyl)-uracil ( 8a ) and -thymine ( 8b ), respectively. A new type of aminoacyl nucleoside, the 1-[5-(aminoacyl)amino-2,3,5-trideoxy-β- d - glycero -pent-2-
摘要通过对相应的3',5'-进行处理,改进了1-(2,3-二脱氧-β-d-甘油-戊-2-烯呋喃糖基)-尿嘧啶(5a)和-胸腺嘧啶(5b)的合成。氧杂环丁烷与氢氧化钠的六甲基磷酸三酰胺溶液。将2',3'-不饱和核苷(5a和5b)转化为1-(5-氨基-2,3,5-三苯氧基-β-d-甘油-戊-2-烯呋喃糖基)-尿嘧啶(8a)和-胸腺嘧啶(8b)。通过缩合缩合得到一种新型的氨基酰基核苷,即1- [5-(氨基酰基)氨基-2,3,5-三苯氧基-β-d-甘油-戊-2-戊呋喃糖基)-尿嘧啶和-胸腺嘧啶。在图8a和8b中,用几种氨基酸衍生物的活性酯进行脱保护。检查了这些核苷对肉瘤180(实体瘤)的体内抗肿瘤活性。但是,没有一种化合物显示出显着的抗肿瘤活性。
