The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.

Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 24807-40-7, name is Methyl 3-(4-(benzyloxy)phenyl)propanoate, A new synthetic method of this compound is introduced below., Recommanded Product: 24807-40-7

To a solution of dimethyl methylphosphonate (1.16 g, 9.33 mmol) in THF (12.5 mL, 0.25 M) at -78 C was added nBuLi (3.9 mL, 9.33 mmol, 2.5 M in hexane). The mixture was stirred for 30 min after which a THF solution (2.5 mL) of ester 11 (750 mg, 3.10 mmol) was added slowly. The reaction mixture was warmed to RT and let stir for 1h, upon which time TLC indicated complete consumption of 11. The reaction mixture was quenched with saturated aqueous NH4Cl (5 mL). The mixture was diluted with H2O (10 mL) and extracted with EtOAc (4 x 25 mL). The combined organic layers were washed with H2O (50 mL), saturated aqueous NaCl (50 mL), dried over MgSO4, filtered, and concentrated in vacuo. Purification by FCC (EtOAc) yielded 12 (1.09 g, 3.01 mmol, 97%) as a clear oil. Data for 12: Rf 0.45 (1:1 Hexanes: EtOAc); IR (thin film) 3034, 2955, 1714, 1512, 1244 cm-1; 1H NMR (700 MHz, CDCl3) delta 7.44 (d, J = 7.5 Hz, 2 H), 7.39 (t, J = 7.6 Hz, 2 H), 7.34 (t, J = 8.6 Hz, 2 H), 6.91 (d, J = 8.6 Hz, 2 H), 5.05 (s, 2 H), 3.76 (d, J = 11.3 Hz, 6 H), 3.08 (d, J = 22.7 Hz, 2 H), 2.94 (t, J = 7.2 Hz, 2 H), 2.87 (t, J = 7.2 Hz, 2H); 13C NMR (176 MHz, CDCl3) delta 201.1, 157.2, 137.1, 132.9, 129.4, 128.6, 127.9, 127.5, 114.9, 70.0, 53.1 (d, J = 6.3 Hz), 45.8, 41.6 (d, J = 128.0 Hz), 28.6; HRMS (ESI) calcd for C19H24PO5 [M+H]: 363.1357, found 363.1361.
