    • Provided is a method for producing a compound represented by general formula (I) by oxidative cleavage of a compound of formula (II), which is a bicyclic tetrasubstituted olefin compound, using hydrogen peroxide. The method for producing a compound represented by general formula (I) includes a step of subjecting a compound represented by general formula (II) to oxidative cleavage using hydrogen peroxide in the presence of an acid catalyst or in the presence of a tungstic acid compound to obtain the compound represented by general formula (I):

      [In the formulae, formula -A 1- (where the front bond denotes a bond that bonds with a carbon atom C 1 while the back bond denotes a bond that bonds with a carbon atom C 2 ) is an alkylene group having 2 to 6 carbon atoms that may have been substituted and that may further include an ether bond, an ester bond, a secondary amino group, a thioether group, or these, and formula -A 2 - (where the front bond denotes a bond that bonds with a carbon atom C 1 while the back bond denotes a bond that bonds with a carbon atom C 2 ) is an alkylene group having 4 to 10 carbon atoms that may have been substituted and that may further include an ether bond, an ester bond, a secondary amino group, a thioether group, or these.]
    • 本发明提供一种通过使用过氧化氢使作为二环式四取代烯烃化合物的式(II)的化合物氧化断裂来制造通式(I)所示的化合物的方法。 通式(I)表示的化合物的制造方法包括在酸催化剂的存在下或在钨酸化合物的存在下,使用过氧化氢使通式(II)表示的化合物氧化分解的步骤, 得到通式(I)所示的化合物:[式中,-A1-(前键表示与碳原子C1键合的键,后键表示与碳原子C2键合的键) 是可以被取代的碳原子数2〜6的亚烷基,还可以进一步具有醚键,酯键,仲氨基,硫醚基或它们,式-A2-(前键 表示与碳原子C1键合的键,而背键表示与碳原子C2键合的键)是可以被取代的具有4至10个碳原子的亚烷基,并且还可以包括醚键, 酯键,一个secon 二芳基氨基,硫醚基或这些。]
