catalyzes the enantioselective oxidation of cyclopropylmethanols. This finding enables a novel route to the synthesis of optically active cyclopropane derivatives, which occur widely in natural products and compounds of pharmaceutical interest. In addition, chiral cyclopropane molecules may be useful model substrates to investigate reaction mechanisms of CPO and the related cytochromes P450.
氯过氧化物酶(CPO)使用叔丁基氢过氧化物作为末端氧化剂,催化环丙基甲醇(例如2-甲基环丙基甲醇)的对映选择性氧化为环丙基醛。在所有情况下,尽管CPO对两种异构体都具有相似的催化活性,但顺式环丙烷的CPO氧化显示出比反式异构体高得多的对映选择性。这是血红素酶催化环丙基甲醇对映选择性氧化的第一个例子。该发现为光学活性环丙烷衍生物的合成提供了一条新途径,该化合物广泛存在于天然产物和具有药物意义的化合物中。此外,手性环丙烷分子可能是研究CPO与相关细胞色素P450反应机理的有用模型底物。
