合成路线 1(1. 合成:13734-36-6)
产率:100%
合成条件:With triethylamine In water for 6 h;
实验步骤:将三乙胺(23.5mL,168.3mmol)和二碳酸二叔丁酯(12.9mL,56.1mmol)依次加入到肌氨酸(5.0g,56.1mmol)的H 2 O(375mL)溶液中,并将混合物搅拌6小时。。 然后加入HCl溶液(320mL,1M水溶液)和EtOAc。 然后分离水层并用EtOAc萃取,干燥(Na 2 SO 4),过滤并真空浓缩,得到无色油状物,其在-15℃下结晶,得到氨基甲酸酯4a(10.6g,定量),为白色固体, 观察到旋转异构体的混合物。
