A series of 2-, 3-, and 4-bromo-1-(methylsulfanyl)benzenes was subjected to whole-cell fermentation withEscherichia coliJM 109 (pDTG601), a recombinant strain that expresses toluene dioxygenase. New metabolites were isolated and their structure and absolute configuration determined by chemical and spectral methods. Experimental details are provided for all new compounds and directing trends in the enzymatic oxidation of substituted aromatics are discussed along with projected applications of these metabolites in asymmetric synthesis.
一系列2-、3-和4-溴代1-(甲硫基)苯被用于与大肠杆菌JM 109 (pDTG601)进行全细胞发酵,这是一株表达甲苯二氧化酶的重组菌株。新代谢产物被分离,并通过化学和光谱方法确定其结构和绝对构型。提供了所有新化合物的实验细节,并讨论了取代芳香族化合物的酶氧化的指导趋势,以及这些代谢产物在不对称合成中的预期应用。
