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。 |

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 |
