With benzotriazol-1-ol; 1-ethyl-(3-(3-dimethylamino)propyl)-carbodiimide hydrochloride; In dichloromethane; at 0 - 20℃; for 21h; | General procedure: A solution of N-Cbz amino acid 4 (1 mmol) and amino alcohol 5a (1 mmol) were dissolved in CH2Cl2(10 mL). To the solution, EDC (1.4 mmol) and HOBT (1 mmol) was added and the solution was stirred at 0 C for 1 h and room temperature for another 20 h. The reaction mixture was quenched with aqueous HCl (0.1 N) and extracted with AcOEt. The combined organic layer was washed with a saturated aqueous NaHCO3, brine, dried over anhydrous Na2SO4, and filterated. The filtrate was concentrated under reduced pressure to give the crude product which was used for the next step without further purification. To asolution of crude N-Cbz amino amide alcohols 6a-n in MeOH (10 mL) was added 5 % Pd/C (10 wt%)under hydrogen atmosphere and the mixture stirred at 50 C for 24 h. The reaction mixture was filtered and the solvent was evaporated under reduced pressure to give the residue. The residue was purified bycolumn chromatography on silica gel (AcOEt : hexane = 1 : 2) to afford the amino amide alcohol 7a-n.Compounds 7j-l were known compounds and were identified by spectral data which were in goodagreement with those reported. |
