実験手順

Prepared using General Procedure 3: To a stirred solution of tert-butyl 2-(((benzyloxy)carbonyl)amino)-3-(4-hydroxy-3-methoxyphenyl)propanoate INT-2 (4.7 g, 11.71 mmol) and TEA (3.05 mL, 21.07 mmol) in DCM (50 mL) at 0° C. was added 4-(heptyloxy)benzoyl chloride (2.95 mL, 12.29 mmol) dropwise. After warming to room temperature and stirring for 10 min, the mixture was quenched with saturated aqueous NaHCO3 (50 mL) and water (50 mL). The organic layer was dried over MgSO4 and concentrated. The product was purified by chromatography (EA/hexanes) to afford 5.46 g (75%) of 4-(2-(((benzyloxy)carbonyl)amino)-3-(tert-butoxy)-3-oxopropyl)-2-methoxyphenyl 4-(heptyloxy)benzoate INT-3. LCMS-ESI (m/z) calculated for C36H45NO8: 619. Found 564 [M+H-tBu]+, tR=3.22 min (Method 4).
