Hydrogenation of pteridines in benzene solution was investigated by solubilising them either as their trimethylsilyl or their 4-benzyloxy derivatives. Using a platinum catalyst, 6,7-dimethyl-4-trimethylsiloxy-2-trimethyl-silylaminopteridine (2) could be converted to -6,7-dimethyl-5, 6,7,8-tetrahydropterin (3), provided that the 4-siloxy group was first selectively cleaved by water. The same silylated
通过将它们溶解为三甲基甲硅烷基或4-苄氧基衍生物来研究蝶啶在苯溶液中的氢化。使用铂催化剂,可以将6,7-二甲基-4-三甲基甲硅烷氧基-2-三甲基-甲硅烷基蝶呤(2)转化为-6,7-二甲基-5,6,7,8-四氢蝶呤(3),条件是首先用水选择性地切割4-甲硅烷氧基。相同的甲硅烷基化蝶啶,(2),与任一的Rh(DIOP)Cl或的[Rh(COD)(DIOP)]无水苯+ CLO 4 - ,经历了新颖脱甲硅烷基化反应,得到6,7- dimethylpterin,( 1),不还原吡嗪环。
