89.3% With lithium hydroxide; In methanol; water;Cooling with ice; General procedure: To a solution of compound 9 (5 mmol) in methanol (50 mL) cooledwith an ice bath was added lithium hydroxide solution (2 M, 50 mL). The mixturewas stirred for 6h, then was acidified to pH 2-3 with hydrochloric acid. Thesolution was concentrated to about halfvolume, then extracted with dichloromethane 3 times (3×50mL).The combined organic layers were dried over anhydrous Na2SO4.After filtration, the filtrate was concentrated to dryness, giving compounds 10. (S)-2-((S)-2-(((benzyloxy)carbonyl)amino)-3-phenylpropanamido)-3-phenylpropanoicacid (10a). Yield: 91.2%.
With lithium hydroxide; In tetrahydrofuran; at 20℃; for 16h; General procedure: The methyl ester (1 equiv.) was dissolved in THF (100 mM). The solution was stirred at 0 C for15 mins. 1M LiOH (5 equiv.) was added slowly to the solution. The mixture was stirred vigorouslyat room temperature for 16 hrs. The mixture was diluted with ethyl acetate and acidified to pH 7with 2M HCl. The aqueous layer was extracted with ethyl acetate (2×25 mL). The combinedorganic layer was washed with brine and dried over sodium sulphate. The solvent was removed invacuo to give the crude product. For details, see individual experiments.

With toluene-4-sulfonic acid;palladium; In ethanol; (a) L-Phenylalanyl-L-leucine, 1,1-dimethylethyl ester, p-toluenesulfonic acid salt p-Toluenesulfonic acid (8.12 g., 42.7 mmole) is added to an ice-chilled solution of <strong>[4313-73-9]N-[N-[(phenylmethoxy)carbonyl]-L-phenylalanyl]-L-leucine</strong>, 1,1-dimethylethyl ester (20 g., 42.68 mmole) in 95% ethanol (325 ml.). The reaction vessel is purged with argon, and 10% palladium on carbon catalyst (2.0 g.) is added. The mixture is placed under 1 atmosphere of hydrogen and stirred for 20 hours. Filtering off the catalyst and concentrating the filtrate produces a sticky white solid which is triturated with ethyl ether and dried in vacuo to give 18.75 g. of L-phenylalanyl-L-leucine, 1,1-dimethylethyl ester, p-toluenesulfonic acid salt; m.p.

With hydrogenchloride;palladium; In phosphorus pentaoxide; ethanol; hexane; (b) L-Phenylalanyl-L-leucine,1,1-dimethylethyl ester, hydrochloride A solution of <strong>[4313-73-9]N-[N-[(phenylmethoxy)carbonyl]-L-phenylalanyl]-L-leucine</strong>, 1,1-dimethylethyl ester (93.72 g., 200.0 mmole) in 95% ethanol (1.5 l.) is hydrogenated under atmospheric pressure hydrogen using a 10% palladium on carbon (6.0 g.) catalyst. After stirring overnight, the mixture is filtered through Celite, concentrated to about 1/2 volume, filtered again, and concentrated to a viscous yellow oil. This oil is taken up in hexane (1.2 l.) and treated, with vigorous stirring, with 200 ml. of 1N hydrogen chloride in ether. The resulting thick, white suspension is diluted with hexane (1 l.), filtered, and washed with additional hexane. Drying overnight in vacuo over phosphorus pentoxide yields 71.80 g. of L-phenylalanyl-L-leucine, 1,1-dimethylethyl ester, hydrochloride as a white solid; m.p. 152.5-154 with bubbling.

With sodium sulfide; 2,4,6-tripropyl-1,3,5,2,4,6-trioxatriphosphinane-2,4,6-trioxide; triethylamine; In acetonitrile; at 0℃; General procedure: To a soln of the appropriate carboxylic acid (1.0 mmol) and T3P (2.2 mmol) in anhyd MeCN (8.0 mL) was added Et3N (1.5 mmol)at 0 C, followed by finely ground Na2S (3.0 mmol). The resulting mixture was stirred for 2-3 h until the reaction was complete (TLC monitoring), concentrated and then diluted with H2O. The mixture was acidified with aq citric acid soln (10%) and the product was extracted with EtOAc (10 mL). The organic layer was washed with H2O (2 × 10 mL) and brine (10 mL), and then dried over anhyd Na2SO4. The solvent was evaporated in vacuo to afford the corresponding amino thioacid in quant. yield.

100% With benzotriazol-1-ol; O-(1H-benzotriazol-1-yl)-N,N,N',N'-tetramethyluronium hexafluorophosphate; N-ethyl-N,N-diisopropylamine; In dichloromethane; at 20℃; for 18h; [000234] To a solution of <strong>[4313-73-9]Z-Phe-Leu-OH</strong> (1000 mg, 2.43 mmol) and Pro-OMe (483 mg, 2.9 mmol) in 20 mL DCM, HBTU (2700 mg, 7.29 mmol), HOBt (328 mg. 2.43 mmol) and DIEA (1567 mg, 12 mmol) were added. The mixture was stirred at rt. for 18 hrs. The solution was washed with 1 N NaHS04, saturated NaHC03 and brine. After drying over anhydrous Na2S04, the solution was concentrated and purified with silica gel column (DCM/MeOH = 100/1 to 50/1) to obtain ZL0176 (1500 mg, quant.) as a white foam. 1H NMR (300 MHz, CDC13) delta 7.39 - 7.29 (m, 5H), 7.27 - 7.22 (m, 3H), 7.16 (m, 2H), 6.70 (d, J = 8.1 Hz, 1H), 5.31 (d, J = 8.2 Hz, 1H), 5.07 (d, J = 3.3 Hz, 2H), 4.78 (td, J = 8.6, 5.2 Hz, 1H), 4.48 (m, 2H), 3.76 (m, 1H), 3.73 (s, 3H), 3.67 - 3.58 (m, 1H), 3.08 (d, J = 6.1 Hz, 2H), 2.29 - 2.15 (m, 1H), 2.12 - 1.94 (m, 3H), 1.70 - 1.41 (m, 3H), 0.98 (d, J = 6.2 Hz, 3H), 0.92 (d, J = 6.4 Hz, 3H). 1 C NMR (300 MHz, CDC13) delta 172.34, 170.74, 170.55, 136.26, 129.38, 128.55, 128.50, 128.12, 128.02, 126.94, 67.02, 58.71, 52.21, 49.07, 46.85, 41.70, 28.98, 24.88, 24.49, 23.26, 21.92.

YieldReaction ConditionsOperation in experiment
75% With benzotriazol-1-ol; 1-ethyl-(3-(3-dimethylamino)propyl)-carbodiimide hydrochloride; N-ethyl-N,N-diisopropylamine; In dichloromethane; water; at 20℃; for 18h; General procedure: To a stirred solution of the N-protected amino acid derivative (1.0 eq) in dry CH2Cl2 (50-75 mM)was added EDC (1.3 eq), HOBt·H2O (1.5 eq) and DIPEA (3.0 eq). The solution was stirred at rtovernight, diluted with CH2Cl2 and the organic layer washed twice with 1M HCl(aq), saturatedaqueous NaHCO3(aq) and brine. The organic layer was dried over MgSO4(s) and the solventremoved in vacuo. See individual experiments for details.
