Abstract:
Boron trifluoride-catalyzed amidoalkylation of indole derivatives with 5-hydroxy-1-phenylimidozolidin-2-one affords new biheterocycles with a direct C–C bond. Among them, 3- or 2-(2-oxoimidazolidin-5-yl)indoles manifest antiinflammatory activity with relatively low toxicity.
Keywords:amidoalkylation, biheterocycles, 3- or 2-(2-oxoimidazolidin-5-yl)indoles, anti-inflammatory activity, indoles, imidazolylindoles.
