(R)-N-叔丁氧羰基-3-碘代丙氨酸甲酯是一种有机中间体,可由Boc-L-丝氨酸甲酯为原料与单质碘反应得到。
制备方法:将20克(91毫摩尔)的Boc-L-丝氨酸甲酯溶解在400毫升四氢呋喃(THF)中,并置于冰水浴中冷却。随后,依次加入36克(137毫摩尔)三苯基膦和14克(177毫摩尔)吡啶,接着分批缓慢加入34克(134毫摩尔)碘,在此过程中保持温度低于20℃反应4小时。
反应完成后,将冰水滴加到反应液中淬灭反应,并用乙醚萃取。所得有机相依次以1%盐酸、5%Na₂SO₃溶液和饱和NaCl溶液洗涤,再用无水Na₂SO₄干燥,过滤并浓缩。最终,将所得残留物溶于石油醚中搅拌析出固体,过滤分离滤渣,并用石油醚洗涤。浓缩滤液得到白色或微黄色固体26克,总产率为87%。
