描述了从[75Se]硒代胱氨酸合成[75Se]三甲基碘化硒。用硼氢化物将起始化合物还原为[75Se]硒代半胱氨酸,并与碘甲烷反应形成[75Se]Se-甲基-硒代半胱氨酸,然后在甲酸溶液中用碘甲烷处理形成Se-二甲基-硒代半胱氨酸碘化硒。经过几天的时间,硒中间体自发消除,形成丙氨酸和二甲基硒化物,二甲基硒化物与碘甲烷反应,得到三甲基硒产品,产率超过 90%。
The synthesis of [75Se]trimethylselenonium iodide from [75Se]selenocystine is described. The starting compound is reduced to [75Se]selenocysteine with borohydride and reacted with methyl iodide to form [75Se]Se-methyl-selenocysteine, then treated with methyl iodide in formic acid solution to form Se-dimethyl-selenocysteine selenonium iodile. Over a period of days, the selenonium intermediate undergoes spontaneous elimination to form alanine and dimethyl selenide, which reacts with methyl iodide to give the trimethylselenonium product in over 90% yield.
