r was dehalogenated with tritium gas to [3-3H]camphor and via [3-3H]phenylborneol converted to [3-3H]deramciclane isolated as the fumarate salt (specific activity 51.8 GBq/mmol). This three step synthesis from [3-3H]camphor gave an overall yield of 22%. Benzyloxy-acetic acid methyl ester was reduced with sodium-borotritide to 2-benzyloxy-ethanol-[1-3H], and through a four step procedure was converted
[(1R)-endo]-(+)-3-溴樟脑用氚气脱卤为[3-3H]樟脑,并通过[3-3H]苯基冰片转化为[3-3H]德环环烷,分离为富马酸盐(特定活性 51.8 GBq/mmol)。由[3-3H]樟脑三步合成的总产率为22%。苄氧基-乙酸甲酯用硼氢化钠还原为 2-苄氧基-乙醇-[1-3H],并通过四步程序转化为 2-二甲氨基乙基-[2-3H]氯化物。后者与 2-苯基冰片的钠衍生物缩合,产生以富马酸盐形式分离的 [2-二甲氨基-[2-3H] 乙氧基]德朗环烷(比活性 8.177 GBq/mmol)。[3H]NaBH4 的六步合成总产率为 6%。版权所有 © 2005 John Wiley & Sons, Ltd.
