“…introduced gold catalysed quinoline synthesis under microwave-assisted conditions. Lewis acids (Hu et al, 2003;McNaughton & Miller, 2003;Zhang & Wu, 2007), Bronsted acids (Muscia et al, 2006), molecular iodine (Wu et al, 2006), proline (Jiang et al, 2008), ionic liquids (Dabiri et al, 2008) and transition metals (Martinez et al, 2007;Gabriele et al, 2007;Vieira &Alper, 2007;Cho & Ren, 2007) were some of the catalysts involved in different synthetic protocols for quinoline structural motif. However many of the aforementioned reactions require strong acids or bases, toxic flammable organic solvents, or hazardous/ expensive catalysts and elevated temperatures.…”
