Synthesis of Mannich bases related to gramine via Mannich reaction of secondary amine, formaldehyde and indole or N-methylindole can be carried out in 69-98% yields in acetic acid aqueous solution at 35°C under ultrasound irradiation. Compared with the method using stirring, the present procedure provided several advantages such as milder conditions, shorter reaction time and higher yield.
在醋酸水溶液中，于 35°C 下超声辐射，通过仲胺、甲醛和吲哚或 N-甲基吲哚的曼尼希反应，可以以 69-98%的产率合成与禾本科有关的曼尼希碱。与使用搅拌的方法相比，本方法具有条件温和、反应时间短、产率高等优点。
