摘要:
A two-step synthetic strategy affords indole-3-acetylcholine (IAC) from indole-3-acetic acid (IAA) via the intermediacy of 2-dimethylaminoethyl indole-3-acetate. Thus, treatment of indole-3-acetate with 1-dimethylamino-2 chloroethane, followed by methylation with methyl iodide, yields 55-70% recrystallized IAC from IAA. Using the same methodology, six analogues of IAC have been prepared in overall yields ranging from 40 to 60%.
