Versuchsvorschrift
To a stirred solution of cis-1-methyl-2,3,3a,4,5,9b-hexahydro-1H-pyrrolo[3,2-h]isoquinoline (120 mg, 0.64 mmol) in AcOH (2 ml) was added 1-iodoundecane (542 mg, 1.92 mmol). The mixture was heated at reflux under nitrogen for 3 days. AcOH was evaporated and the residue was dissolved in CHCl3. The mixture was washed with saturated aqueous NaHCO3, water and brine successively and dried. Evaporation of the solvent followed by titration with ether afforded 210 mg (70%) of cis-1-methyl-8-undecyl-2,3,3a,4,5,9b-hexahydro-1H-pyrrolo[3,2-h]isoquinolin-8-ium iodide (ACU) as a brown oil. 1H NMR (300 MHz, CDCl3) δ9.16 (1H, s, C9-H), 9.07 (1H, d, J6.0 Hz, C7-H), 7.81 (1H, d, J6.0 Hz, C6-H), 4.82 (2H, m. pyCH2), 3.44 (1H, d, J8.4 Hz, C9b-H), 2.29 (3H, s, NCH3), 1.50-3.10 (9H, m, CH2+CH), 1.95 (2H, m, pyCH2CH2), 1.00-1.40 (16H, m, 8×CH2), 0.76 (3H, t, J6.9 Hz, CH2CH3); 13C NMR (75 MHz, CDCl3) δ161.5, 143.2, 142.4, 138.8, 127.5, 63.1, 61.0, 55.7, 41.0, 35.6, 32.0, 31.8, 30.0, 29.51, 29.48, 29.4, 29.2, 29.1, 28.1, 27.3, 26.0, 22.6, 14.1.
