Route of Synthesis (ROS)

Route of Synthesis (ROS) of Propanoic acid, 2,2-dimethyl-, 1,1',1',1'''-] ester CAS 134606-34-1

ConditionsYieldWith potassium hydroxide In toluene at 40℃; for 8h;Experimental Procedurea.35 Preparation of compound 46-5:To a solution of 46-4 (3.3 g, 12.6 mmol) in toluene (30 mL) was added POM ester (7.9 g, 12.6 mmol) and KOH (1.3 g, 22.6 mmol) at room temperature. The reaction mixture was stirred at 40°C for 8 hours. LCMS showed 46-4 was consumed. The mixture was diluted with water and EA was added. The product was extracted with EA. The organic layer was washed with brine and dried over Na2SO4and concentrated to give the crude. The crude was purified by Flash-Prep-HPLC with the following conditions (IntelFlash-1): Column, C18 silica gel; mobile phase, CH3CN/H2O (0.5% NH4HCO3) = 1/1 increasing to CH3CN/H2O (0.5% NH4HCO3) = 1/0 within 20 min, the eluted product was collected at CH3CN/H2O (0.5% NH4HCO3) = 91/9 Detector, UV 254 nm. This resulted in 46-5 (5.4 g, 9.5 mmol, 75.9% yield) as an oil. ESI-LCMS: m/z 567.2 +; 1H-NMR (400 MHz, CDCl3) δ 6.89-6.77(m, 1H), 6.07-5.96(m, 1H), 5.86-5.55(m, 4H), 4.85 -4.73(m, 1H), 4.36-4.27(m, 1H), 4.05-3.96(m, 1H), 3.95-3.85(m, 1H), 3.73-3.65(m, 1H), 3.44-3.35 (m, 3H), 1.30-1.25(s, 18H), 0.94-0.84(s, 9H), 0.14-0.05(s, 6H). 31P-NMR (162 MHz, CDCl3) δ 18.30, 15.11.75.9%
