Abstract A palladium-catalyzed coupling of iodoaniline 2 with bis-TES propargyl alcohol 3 gives indole-3-methanol 4b in 72% yield. Displacement of the hydroxy group of 4b by sodium cyanide followed by hydrolysis of the cyano group and desilylation provides the indole acetic acid metabolite, L-749,335 (1), of the 5-HT1D receptor agonist MK-0462.
摘要 碘苯胺 2 与双-TES 炔丙醇 3 的钯催化偶联得到吲哚-3-甲醇 4b,产率为 72%。用氰化钠置换 4b 的羟基,然后水解氰基和脱甲硅烷基,得到 5-HT1D 受体激动剂 MK-0462 的吲哚乙酸代谢物 L-749,335 (1)。
