실험 절차

In a 100 mL round bottom flask, N-Boc-L-proline (1.0 mmol), coupling reagent (520 mg of PBOP or 380 mg of HATU, 1 mmol) and N,N-diisopropyl-ethyl-amine (650 mg, 5 mmol) were mixed in CH2Cl2 (10 mL). The reaction mixture was stirred at room temperature for 30 minutes. S-trans, trans-farnesyl-L-cysteine (325 mg, 1 mmol) was added to the reaction mixture. The reaction mixture was stirred at room temperature overnight. CH2Cl2 was removed by rotary evaporation. The resulting residue was dissolved in ethyl acetate (50 mL). The organic solution was washed with an NH4Cl saturated solution (50 mL), dried over Na2SO4, and concentrated to afford a crude mixture. The crude mixture was purified by preparative HPLC (232 mg, 44%) to yield Compound N-8. 1H-NMR (500 MHz, CDCl3): δ 1.46 (s, 9H), 1.62 (bs, 6H), 1.69 (s, 3H), 1.72 (s, 3H), 1.89 (bs, 1H), 1.98 (t, J=7.5 Hz, 2H), 2.05-2.14 (m, 6H), 2.24-2.26 (m, 1H), 2.79 (dd, J=8.0, 14.0, 1H), 3.03 (bd, J=13.0 Hz, 1H), 3.15 (dd, J=7.5, 13.0 Hz, 1H), 3.27 (dd, J=8.0, 13.0 Hz, 1H), 3.40 (m, 1H), 3.66 (bs, 1H), 4.28 (bs, 1H), 4.60 (dd, J=4.9, 8.0 Hz, 1H), 5.11-5.14 (m, 2H), 5.24 (t, J=7.4 Hz, 1H). 13C-NMR (125 MHz, CDCl3): δ 16.2, 16.3, 17.8, 24.2, 24.5, 25.3, 25.9, 27.4, 27.8, 28.7, 30.1, 30.4, 30.7, 31.1, 32.5, 33.5, 40.8, 40.9, 47.9, 48.3, 53.1, 53.4, 61.4, 61.9, 81.4, 81.7, 121.5, 125.1, 125.5, 132.1, 136.3, 140.5, 156.2, 173.6, 175.8; ES-MS: mass calcd for Chemical Formula: C28H46N2O5S 522.3.
