A method for producing an optically active lactone compound by Baeyer-Villiger oxidation of a cyclic ketone compound with at least one kind of oxidants selected from the group consisting of hydrogen peroxide and urine-hydrogen peroxide adduct (UHP) using a cobalt(salen) complex having a cis-&bgr; structure expressed by the following formula (I) or (II) as a catalyst.
1
in which X and Y independently denote H, a t-butyl group or an electron-withdrawing substituting group and W is a halogen element.
2
in which X and Y independently denote H, a t-butyl group or an electron-withdrawing substituting group and Z
−
is a monovalent anion. The optically active lactone compounds can be used for the synthesis of medicines and argochemicals.
通过使用具有以下公式(I)或(II)所表示的具有顺式&bgr;结构的
钴(salen)配合物作为催化剂,通过将环状酮化合物与氢过氧化物和
尿素-氢过氧化物加合物(UHP)中至少一种氧化剂进行巴耶-维利格氧化,制备光学活性内酯化合物的方法。其中X和Y独立地表示H、叔丁基或带有吸电子取代基,W是卤素元素。X和Y独立地表示H、叔丁基或带有吸电子取代基,Z-是一价阴离子。这些光学活性内酯化合物可用于合成药物和农药。
