以L-苯丙氨酸为原料,与甲醇发生甲酯化反应后,在Et3N/MeOH条件下进行Boc保护,制备得到N-叔丁氧羰基-L-苯丙氨酸甲酯。其制备反应式如下:
图1 N-叔丁氧羰基-L-苯丙氨酸甲酯制备反应式
L-苯丙氨酸甲酯盐酸盐的制备在500 mL四口反应瓶中,加入L-苯丙氨酸和无水甲醇300 mL,搅拌并降温至0-5℃。在此温度下滴加氯化亚砜约1小时,保温反应1小时后升温回流反应4小时。反应完毕后减压蒸出甲醇和过量的氯化亚砜至干,得到白色固体L-苯丙氨酸甲酯盐酸盐。
N-叔丁氧羰基-L-苯丙氨酸甲酯的制备在100 mL单口反应瓶中,将2. 15 g L-苯丙氨酸甲酯溶于30 mL甲醇。缓慢加入三乙胺(3. 5 mL,25 mmol)和Boc酸酐(4. 6 mL,20 mmol),加热升温至40 ℃并搅拌反应5小时。减压浓缩除去剩余甲醇后用乙酸乙酯萃取反应液,有机相经蒸馏水洗涤三次、饱和氯化钠水溶液洗涤一次,并用无水硫酸钠干燥。过滤后浓缩得到粗品N-叔丁氧羰基-L-苯丙氨酸甲酯,经柱层析纯化获得2. 59 g无色透明油状物。
