5-carboxymethylaminomethyl(-2-thio)uridine (cmnm5(s2)U) and 5-taurinomethyl(-2-thio)uridine (τm5(s2)U) with a blocked amino acid function. 2-(Trimethylsilyl)ethyl and 2-(p-nitrophenyl)ethyl esters of glycine and 2-(2,4,5-trifluorophenyl)ethyl ester of taurine were selected as protection of carboxylic and sulfonic acid residues, respectively. The first synthesis of 5-formyl-2′,3′-O-isopropylidene-2-thiouridine
在本文中,我们讨论了在三乙酰氧基硼氢化钠(NaBH(OAc)3)存在下,用甘氨酸或牛磺酸酯对5-甲酰基-2',3'-O-异亚丙基(-2-硫基)尿苷进行氨基化还原胺化的有用性。用于合成天然线粒体(mt)tRNA组分5-羧甲基氨基甲基(-2-硫代)尿苷(cmnm5(s2)U)和5-牛磺基甲基(-2-硫代)尿苷(τm5(s2)U)氨基酸功能。分别选择甘氨酸的2-(三甲基甲硅烷基)乙酯和2-(对硝基苯基)乙酯和牛磺酸的2-(2,4,5-三氟苯基)乙酯作为羧酸和磺酸残基的保护剂。还报道了5-甲酰基-2',3'-O-异亚丙基-2-硫尿苷的首次合成。
