摘 要:(R)-(-)-α-甲氧基苯乙酸的2種合成方法均是以簡(jiǎn)單易得的扁桃酸為原料,經(jīng)醚化,或者經(jīng)酯化醚化、水解得單一構型(R)-(-)-α-甲氧基苯乙酸,其結構經(jīng)MS、1H NMR、13C NMR分析確證。產(chǎn)品純度99.3%(HPLC),反應收率52.0%。路線(xiàn)一方法與原有文獻相比,后處理操作簡(jiǎn)單、耗時(shí)短、收率高,而路線(xiàn)二方法是無(wú)文獻報道的全新方法。2種方法均利于工業(yè)化生產(chǎn)。 |

Abstract:(R)-2-Methoxy-2-phenylacetic acid was synthesized from mandelic acid via esterification-etherification and hydrolysis,or via only a single step of etherification. Its structure was confirmed by MS,1H NMR and 13C NMR. The purity of the product was 99.3% (HPLC),and overall yield was 52.0%. The former method shows the advantages of convenient operation,time saving and high yield,whereas the latter is a novel way never reported. These two methods are both suitable for industrial process. |
Key words:(R)-2-methoxy-2-phenylacetic acid;mandelic acid;etherification;esterification ;hydrolysis |
