benzyloxyacetic acid - Reference Information
| Use | Benzyloxyacetic acid can be used as an intermediate in pharmaceutical chemistry and organic synthesis. In the synthetic transformation, the carboxyl group in the structure can be easily converted into ester groups or reactive functional groups such as hydroxyl groups. In the reported literature, the most commonly used method is to convert the carboxyl group into acid chloride, the benzyl group can then be connected to the target molecular structure through the conversion of acid chloride. In addition, the benzyl group in the structure can be removed by palladium-carbon hydrogenation under reacidic conditions to obtain the corresponding hydroxy acid product. |
| Synthesis method | Cool the reaction bottle to 0 degrees in an ice water bath, and dissolve sodium hydride (60% dispersed in a solution of tetrahydrofuran (100ml) in 10 minutes In mineral oil, 330 mmol) suspension is added to benzyl alcohol (38.8 ml, 375 mmol), pay attention to the reaction will obviously appear bubbles, during operation, the pressure balance in the reaction bottle should be kept as much as possible, and the bubbles should stop coming out. Under the condition of cooling, the solution of bromoacetic acid (150mmol) in tetrahydrofuran (50mL) should be added within 10 minutes. After adding, the ice bath should be removed, the mixed solution should be stirred at ambient temperature for 12 hours, and then the mixed solution of water (150mL) and n-hexane (100mL) should be slowly added into the reaction system, dissolve the reaction system in this biphasic mixture, separate the water layer, acidify the water layer with concentrated hydrochloric acid (12M,40mL), then extract the water layer with diethyl ether (2 × 100 mL), clean the combined organic extract with brine (50 mL), dry the combined organic extract with anhydrous magnesium sulfate, and filter to remove the concentrated organic extract of magnesium sulfate solid to obtain benzyloacetic acid.
