The oxidative oligomerization of a chiral mandelamide derivative (N-(4-hydroxyphenyl)mandelamide, 1) was performed in the presence of horseradish peroxidase, laccase and N,N'-bis(salicylidene)ethylenediamine-iron(II) to obtain chiral oligophenols 2. The low enantioselectivity of the enzymatic catalyzed asymmetric enantiomer-differentiating oligomerizations was investigated. In addition, the poor influence of cyclodextrin on the enantioselectivity of enzymatic catalyzed asymmetric enantiomer-differentiating oligomerizations was studied.
在辣根过氧化物酶、漆酶和N,N'-双(水杨醛)乙二胺-铁(II)的存在下,对手性曼德酰胺衍生物(4-羟基苯基)曼德酰胺(1)进行氧化寡聚反应,得到手性寡酚2。研究了酶催化的不对称对映异构体分化寡聚反应的低对映选择性。此外,还研究了环糊精对酶催化的不对称对映异构体分化寡聚反应对对映选择性的影响较差。
