The laccase‐catalyzed oxidation of a series of substituted 4‐hydroxy‐chalcones has been investigated. The main isolated dimeric products were, as expected, racemic mixtures of trans‐2,3‐dihydrobenzofuran derivatives, always co‐eluted with an additional isomeric dimer with an open structure. The two enantiomers, as well as the co‐eluted dimeric isomer could be isolated by semi‐preparative HPLC with
已经研究了漆酶催化的一系列取代的4-羟基查耳酮的氧化。如预期的那样,主要的分离二聚产物是反式-2,3-二氢苯并呋喃衍生物的外消旋混合物,总是与具有开放结构的其他异构二聚体共洗脱。两种对映体以及共洗脱的二聚体异构体可通过半制备型HPLC用手性柱进行分离并进行充分表征。
