YieldReaction ConditionsOperation in experiment
40% Cyclohexylamine (2.70 mL, 23.1 mmol) was added to a mixture of compound 8 (1.54 g, 11.5 mmol) and molecular sieves 4 A (4.0 g) in benzene (50 mL) at 0 °C and then stirred for 1 h at room temperature. Insoluble materials were filtered off through Celite, then the filtrate was concentrated. The obtained intermediate was dissolved in THF (30 mL), then a solution of LDA in hexane-THF (10.1 mL, 11.5 mmol) and t-butyl(2-iodoethoxy)dimethylsilane (3.30 g, 11.5 mmol) was 4.2.2 4-(2-t-Butyldimethylsilyloxyethyl)-2,2-dimethyl-1,3-dioxane-5-one (9) added at -78 °C. The mixture was stirred for 18 h at room temperature, then the reaction was quenched with saturated aqueous ammonium chloride. The mixture was extracted with ethyl acetate, washed with brine, dried with Na2SO4 and then concentrated. Purification by silica gel column chromatography (eluent; n-hexane/ethyl acetate; 30:1) gave compound 9 (1.32 g, 40percent) as yellow oil. 1H NMR (400 MHz, CDCl3) delta 4.44 (m, 1H), 4.28 (dd, J = 16.9 Hz, 1.4 Hz, 1H), 3.99 (d, J = 16.9 Hz, 2H), 3.74-3.70 (m, 2H), 2.16-2.08 (m, 1H), 1.70-1.58 (m, 1H), 1.46 (s, 3H), 1.43 (s, 3H), 0.88 (s, 9H), 0.05 (s, 6H).
