| | 3,4-Dimethoxyphenylacetone Usage And Synthesis |
| Chemical Properties | CLEAR YELLOW TO BROWN LIQUID | | Uses | 3,4-Dimethoxyphenylacetone was used as starting material in the synthesis of α-methyl-dopa, an important nonproteogenic α-amino acid for pharmaceutical applications. 3,4-Dimethoxyphenylacetone undergoes asymmetric amination catalyzed by Brevibacterium linens IFO 12141 strain to yield corresponding optically active amine | | Synthesis Reference(s) | Chemistry Letters, 5, p. 1239, 1976
The Journal of Organic Chemistry, 29, p. 1424, 1964 DOI: 10.1021/jo01029a039 | | Synthesis | GENERAL METHOD: To a THF/water (4:1, 15 mL) solution of methyl eugenol (1 mmol) was added 10% Pd/C (0.05 mmol) and KBrO3 (3 mmol). The reaction mixture was heated to reflux temperature. The reaction progress was monitored by TLC. After completion of the reaction, the mixture was diluted with water and filtered through Whatman 40 filter paper. The filtrate was extracted with ethyl acetate and the organic layers were combined. The organic layers were washed sequentially with water, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The crude product was purified by column chromatography to give 3,4-dimethoxypropiophenone. | | References | [1] Tetrahedron Letters, 2013, vol. 54, # 19, p. 2293 - 2295
