摘 要:利用三光氣為;瘎,芳胺在-5℃的條件下與單叔丁氧羰基保護的哌嗪反應,“一鍋法”生成4-叔丁氧羰基哌嗪甲酰胺。然后在濃鹽酸的二氧六環(huán)溶液中脫除叔丁氧羰基,得哌嗪甲酰胺衍生物。討論了鹽酸的用量對保護基脫除效率的影響。 |
關(guān)鍵詞:哌嗪甲酰胺;三光氣;叔丁氧羰基 |

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 |
