Aluminium lithium hydride → HCID 178448134, compound

Participants

Reaction Steps

To a solution of 300 mg (0.95 mmol) of enoate (138) in 2.0 mL of anhydrous tetrahydrofuran at 25° C. was added 18 mg (0.43 mmol) of lithium aluminum hydride and the resulting mixture was allowed to stir for 30 min.The reaction was quenched by the slow addition of saturated Rochelle's saltand diluted with ethyl acetate. The layers were separated and the aqueous layer was extracted with two portions of ethyl acetate. The combined organic extracts were washed with water and brine and then dried over MgSO4. Evaporation and flash chromatography (elution with 1:10 ethyl acetate-hexane) gave 220 mg of the allyic alcohol (139). 1H NMR (300MHz, CDCl3) δ 5.34 (d), 3.96 (d), 3.85 (m), 2.26-2.18 (m), 1.64 (d), 1.61-1.34 (m), 1.82 (s), 0.0 (s).
