保护基策略法合成哌嗪甲酰胺衍生物
蒋达洪,范 芳 (广东石油化工学院 化学与生命科学学院,广东 茂名,525000)
摘 要:利用三光气为酰化剂,芳胺在-5℃的条件下与单叔丁氧羰基保护的哌嗪反应,“一锅法”生成4-叔丁氧羰基哌嗪甲酰胺。然后在浓盐酸的二氧六环溶液中脱除叔丁氧羰基,得哌嗪甲酰胺衍生物。讨论了盐酸的用量对保护基脱除效率的影响。

Synthesis of Piperazinyl Formamide Derivatives
JIANG Da-hong,FAN Fang (Department of Chemistry and Life Science,Guangdong University of Petrochemistry Technology,Maoming 525000,China)
Abstract:N-Boc-Piperazinyl formamides were synthesized in “one-pot” procedure from aryl amines,triphosgene and N-boc-piperazine at -5℃. The protective group of boc was eliminated to give piperazinyl formamide derivatives in a solution of HCl in dioxane. The effect of the concentration of HCl was discussed.
Key words:piperazinyl formamides;triphosgene;boc
