1,10-Decanediol → HCID 86665351, compound

Participants

Reaction Steps

In a 500 mL round-bottomed flask was cholesteryl tosylate (10.0 g, 18.5 mmol) and 1,10-Decanediol (48.3 g, 277 mmol) suspended in Dioxane (200 ml) to give a white suspension. The flask was fitted with a temperature sensor and reflux condenser. The mixture was heated to reflux and allowed to stir at reflux overnight. The reaction mixture was cooled to room temperature and the solids were filtered off. The solution was concentrated in vacuo. The mixture was re-dissolved in methanol (250 mL) and water (ca. 40 mL) was added to precipitate out the crude product. The precipitate was filtered and dried in vacuo. The residue was further purified via column chromatography on a 100 g Biotage SNAP column eluting over 2 L of a 0-25% EtOAc in Hexanes gradient. Pure fractions were combined and concentrated to give 7.85 g (82%) of a white solid. 1H NMR (300 mHz, CDCl3) δ0.69 (3H, s); 0.85-1.66 (50H, m); 1.75-2.09 (5H, m); 2.14-2.29 (1H, m); 2.32-2.43 (1H, m); 3.14 (1H, tt, J=11.2, 4.4 Hz); 3.46 (2H, dt, J=6.9, 0.4 Hz); 3.65 (2H, t, J=6.6 Hz); 5.36 (1H, d, J=5.3 Hz).
