Abstract: Functionalized indoles are synthezised under mild conditions in a tartaric acid–dimethylurea melt. The melt serves as the solvent and as the catalyst. Under these reaction conditions, sensitive functional groups such as N-Boc, N-Cbz, or azides are stable, Cited by: applied to the synthesis of eletriptan (Scheme 7), and the reduc-tion step has also been demonstrated in ow Scheme 3 Classical routes to indoles from ortho-substituted anilines. Scheme 4 The Fischer indole synthesis. Scheme 5 Garg’s synthesis of aspidophylline using a Fischer indole approach.
