Reaction Conditions

Reaction Steps

Zinc dust (24.42 g, 373.3 mmol) was added to a solution of 46 (16.28 g, 28.42 mmol) in acetic acid (150 mL). The mixture was then heated to reflux (115° C.) for 3 h. The mixture was then concentrated in vacuo, and the residual pyridine removed by dissolving the residue in toluene (100 mL) and concentrating in vacuo. The resulting residue was by silica gel chromatography, eluting with a gradient of 0% through 30% ethyl acetate/hexanes to provide (R)-benzyl 3-(tetradecanoyloxy)tetradecanoic acid (47, 11.14 g, 86% yield) as a colorless oil. 1H NMR (CDCl3) δ 5.29-5.18 (m, 1H), 2.62-2.55 (m, 2H), 2.34-2.25 (m, 2H), 1.65-1.58 (m, 3H), 1.28-1.20 (m, 40H), 0.85 (m, 6H).
