5-isopropyl-2-thiouracil derivatives 13 and 14 by the above procedure following oxidative hydrolysis of the thione. Preparation of the target 5-alkyl-1-(alkoxymethyl)-6-benzyluracil derivatives 27-34 was carried out by acetylation of 9-14 followed by Pd-catalyzed hydrogenolysis. The 1-butyl- (37 and 39) and 1-(2-methoxyl)- (38 and 40) 5-alkyl-6-benzyluracils were synthesized by 1-alkylation of the 3-phenacyl
合成了1-[((2-羟基乙氧基)甲基] -6-(苯硫基)胸腺嘧啶(1; HEPT)的几种6-苄基类似物,并评估了它们的抗HIV-1活性。LDA(二异丙基氨基锂)锂化5-乙基尿嘧啶衍生物7和8,随后与芳基醛反应,得到6-(芳基羟甲基)-5-乙基尿嘧啶衍生物9-12。在硫酮氧化水解之后,通过上述程序由5-异丙基-2-硫尿嘧啶衍生物13和14制备6-(芳基羟甲基)-5-异丙基尿嘧啶衍生物15-18。通过9-14的乙酰化,然后Pd催化的氢解,进行目标5-烷基-1-(烷氧基甲基)-6-苄基尿嘧啶衍生物27-34的制备。1-丁基-(37和39)和1-(2-甲氧基)-(38和40)5-烷基-6-苄基尿嘧啶是通过将3-苯甲酰基衍生物35和36与卤代烷进行1-烷基化反应合成的通过去保护3-苯甲酰基。在这项研究中合成的化合物在亚微摩尔至纳摩尔浓度范围内抑制MT-4细胞中的HIV-1复制。从这一系列化合物中,选
