실험 절차

In a 100 mL RBF fitted with reflux condenser, compound 10 (4 g, 6.69 mmol) was dissolved in 26 mL THF for addition of the lithium aluminum hydride (13.38 ml, 13.38 mmol). Heated to reflux in a 85 C. oil bath. After 2 h, HPLC shows complete dissappearance of the SM. Cooled to RT and poured into 200 mL IM K2CO3 and 200 mL MTBE. Stirred for 30 min, separated layers and then extracted with 100 mL MTBE. Dried combined organics over Na2SO4, filtered through Celite and concentrated. Flash chromatography (10-30% IPA in DCM) provided compound 11 as a clear oil. 1H NMR (400 MHz, CDCl3) δ 5.39 (m, 4H), 3.93 (m, 2H), 3.50 (m, 4H), 3.04 (m, 2H), 2.79 (m, 2H), 2.48 (m, 2H), 2.39 (s, 3H), 2.08 (m, 4H), 1.62 (m, 4H), 1.40-1.25 (m, 26H), 0.91 (m, 6H).
