    • General procedure for the preparation of compounds 5a-1: The corresponding cycloadduct (4, 1.0 mmol) was dissolved in CHCl3 (10 mL) and NBS (0.17 g, 1.1 mmol) was added in one portion. The solution immediately turned yellow. After 30 min stirring H2O (10 mL) was added and the organic layer was washed with further portions of H2O (2 x 10 mL) and brine (10 mL, then dried (MgSO4) and evaporated in vacuo. The residue was triturated with cold EtOH and filtered to yield the title product as a yellow powder. All new compounds afforded correct elemental analyses and spectroscopic data. Selected examples: Methyl 8,9-dimethoxy-1- nitro-2-phenyl-5,6-dihydropyrrolo[2,1-a]isoquinoline-3-carboxylate (5a, IR (KBr, 2956, 2833, 1700, 1609, 1591, 1561, 1547, 1506, 1452, 1439, 1355, 1284, 1262, 1236, 1217, 1195, 1181, 1136, 1100, 1072, 1016 cm -1; 1H NMR (500 MHz, CDCl3, δ, 7.39 m, 4 H, Ph
