实验步骤: To a mixture of 1H-indole-4-carboxylic acid (322 mg, 2.00 mmol), tert-butyl 3-(2-(2-(2-aminoethoxy)ethoxy)ethoxy)propanoate (554 mg, 2.00 mmol), and diisporopylethylamine (700 μL, 4.00 mmol) in DMF (3 mL) was added HATU (950 mg, 2.50 mmol) and the solutions stirred for 16 h. The solvent was removed and the resulting residue was purified by silica gel chromatography, using a gradient of 70% to 100% EtOAc in hexanes as eluent and the solvent removed. This gave 557 mg (66%) of the product. The solvent was removed the resulting residue was purified by silica gel chromatography the solvent removed

实验步骤: To a solution of (R)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(((R)-2,3-bis(dodecyloxy)propyl)thio)propanoic acid (1 eq, from example 20, step 5) and HBTU (1.2 eq) in DCM (0.06 M) was added DIEA (3.5 eq), followed by tert-butyl 3-(2-(2-(2-aminoethoxy)ethoxy)ethoxy)propanoate (1.2 eq). The reaction was stirred at room temperature for 2 hours. The crude mixture was purified by flash chromatography on a COMBIFLASH® system (ISCO) using 0-5% MeOH/DCM to give the title product as a white solid.

实验步骤: A solution of 4-[4-(3,5-dioxo-hexyl)-phenylcarbamoyl]-butyric acid 2,5-dioxo-pyrrolidin-1-yl ester (1.5 g, 3.6 mmol), 3-{2-[2-(2-amino-ethoxy)-ethoxy]-ethoxy}-propionic acid tert-butyl ester (1.0 g, 3.6 mmol) and DIEA (1.3 μL, 7.2 mmol) in CH2Cl2 (10 mL) was stirred at rt overnight. The solvent was removed in vacuo and the residual oil purified using column chromatography EtOAc/MeOH (95:5) to give the title compound as a transparent oil, (M+1)=579. The solvent was removed in vacuo the residual oil purified

实验步骤: NaN3 (35 g, 538 mmol) was added to a stirring solution of 3-{2-[2-(2-tosylsulfonyloxy-ethoxy)-ethoxy]-ethoxy}-propionic acid tert-butyl ester (20 g, 46 mmol) in DMF (150 mL) and the reaction was stirred overnight. Reaction was diluted with water (200 mL) and extracted with EtOAc (4×100 mL). The organic layer was washed with water (100 mL) and brine (100 mL) and dried over Na2SO4. The solvent was removed in vacuo to give an oil. Column chromatography EtOAc/Hex (1:4) gave an oil which corresponds to the 3-{2-[2-(2-azido-ethoxy)-ethoxy]-ethoxy}-propionic acid tert-butyl ester, (M+1)=304. This oil was hydrogenated using Pd (5% on carbon) in EtOAc under hydrogen (1 atm.) over 3 days. The catalyst was removed by filtration and solvent removed in vacuo to give an oil corresponding to the title compound, (M+1) 278. Reaction extracted with EtOAc (4×100 mL) The organic layer was washed with water (100 mL) and brine (100 mL) dried over Na2SO4 The solvent was removed in vacuo to give an oil over 3 days The catalyst was removed by filtration and solvent removed in vacuo
