dioxygenase-catalysed cis-dihydroxylation of monosubstituted benzene substrates, have been used as synthetic precursors of the corresponding trans-3,4-dihydrodiols. The six-step chemoenzymatic route from cis-dihydrodiol precursors, involving acetonide, tetraol, dibromodiacetate and diepoxide intermediates, and substitution of vinyl bromide and iodide atoms, has been used in the synthesis of ten trans-dihydrododiol derivatives
可从单取代苯底物的双加氧酶催化的顺式-二羟基化获得的对映体纯的顺式2,3-二氢二醇已用作相应的反式3,4-二氢二醇的合成前体。顺式-二氢二醇前体的六步化学酶法路线涉及乙醛,四醇,二溴二乙酸酯和二环氧化合物中间体,以及乙烯基溴和碘原子的取代,已用于合成十种取代苯的反式-二氢二二醇衍生物。该方法在甲苯的反式1,2-和3,4-二氢二醇衍生物的两种对映异构体的合成中的使用已经证明了该方法的普遍适用性。
