1	A New Approach to Benzo[h]quinoline Skeleton Huang, Chiao-wei 25 July 2007 (has links) We use stepwise [3+3] annulation to prepare the asymmetric glutarimides, and then we can build substituent group in C6 position after choosing regioselective addition reaction. And we establish a new approach to benzo[h]quinoline skeleton starting from glutarimides via ring-closing reaction. Finally, we applied this method to the synthetic studies toward benzo[h]quinoline derivatives. benzo[h]quinoline derivatives regioselective addition reaction [3+3] annulation
