Biotransformation of 3-substituted and 2,5-disubstituted phenols, using whole cells of P. putida UV4, yielded cyclohexenone cis-diols as single enantiomers; their structures and absolute configurations have been determined by NMR and ECD spectroscopy, X-ray crystallography, and stereochemical correlation involving a four step chemoenzymatic synthesis from the corresponding cis-dihydrodiol metabolites
使用恶臭假单胞菌UV4的整个细胞对3-取代的和2,5-二取代的酚进行生物转化,产生了环己烯酮顺式-二醇作为单一对映体。它们的结构和绝对构型已通过NMR和ECD光谱,X射线晶体学以及涉及从相应的顺式-二氢二醇代谢物进行四步化学酶法合成的立体化学相关性确定。已经提出了活性位点模型,以解释具有相反绝对构型的对映纯环己烯酮顺式-二醇的形成。
