[Fe(F20TPP)Cl] catalyzed intramolecular C–N bond formation for alkaloid synthesis using aryl azides as nitrogen source†
Abstract
The syntheses of alkaloids including indoles, indolines, tetrahydroquinolines, dihydroquinazolinones and quinazolinones have been accomplished in moderate to excellent yields via [Fe(F20TPP)Cl] catalyzed intramolecular C–N bond formation using aryl azides as
