1 Source of material
Aspirin acylchloride was synthesized according to the literature method. 4 4-Hydroxy-3-methoxybenzaldehyde (0.01 mol, 1.52 g) and 4-(dimethylamino)-pyridin (DMAP, 0.0015 mol, 0.18 g) were dissolved in dry tetrahydrofuran (20 mL) and triethylamine (0.015 mol, 2 mL). The solution of aspirin acylchloride in dry tetrahydrofuran was dropwise added at 0 °C. The reaction mixture was stirred for 2 h at room temperature. The reaction mixture was filtrated and the filtrate was concentrated under vacuum. The residue was dissolved in dichloromethane, successively washed with 5 % NaOH solution and water to pH = 7, and dried with anhydrous Na2SO4. The solution was filtrated, and concentrated under vacuum. The crude product was purified by recrystallization in ethanol. The crystals were obtained from tetrahydrofuran.
2 Experimental details
Coordinates of hydrogen atoms were refined with constraints. The U iso values were set to be 1.5U eq of the carrier atom for methyl H atoms and 1.2U eq for remaining H atoms.
3 Comment
Aspirin is a classic and effective drug that has been widely used for over a century to treat inflammation, fever, and pain. 5 Recently, aspirin has received renewed attention due to its potential benefits in preventing/treating cancer. 6 , 7 However, the long-term use of aspirin is limited because it lacks COX-2 selectivity, which is often considered the main drawback of aspirin and the cause of its main side effects such as gastric ulceration. 8 Some newly synthesized aspirin derivatives exhibit incredible good anti-tumor activity. Although the anti-tumor mechanism of aspirin is complex, there are also some mainstream approaches. In order to achieve efficient, low toxicity, and low-cost anti-tumor drugs, we chose aspirin as the core compound and modified its structure.
The title compound contains two benzene rings. The bond distances of C–O are 1.4016(14) Å (C5–O3), 1.3655 (13) Å (C9–O3), 1.3970 (13) Å (C15–O6), 1.3654 (14) Å (C16–O6), 1.2005 (14) Å (C9–O4), 1.2013 (14) Å (C16–O5), 1.3585 (14) Å (C6–O2), 1.4335 (15) Å (C8–O2), and 1.2101 (18) Å (C1–O1), respectively. The bond distance of C9–O4, C1–O1 and C16–O5 are shorter than those of C5–O3, C9–O3, C15–O6, C16–O6, C6–O2 and C8–O2, indicating C9–O4, C1–O1 and C16–O5 are double bonds. The dihedral angle of ring 1 (C2–C3–C4–C5–C6–C7) and ring 2 (C10–C11–C12–C13–C14–C15) is 81.275(48)°. The other bond distances and angles are in their normal ranges according to the previously reported compounds. 9 – 11
