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.]
提供了一种通过使用过氧化氢对式为(II)的双环四取代烯烃化合物进行氧化裂解来制备通式(I)化合物的方法。制备通式(I)化合物的方法包括以下步骤:将通式(II)化合物在酸催化剂或钨酸化合物存在下,使用过氧化氢进行氧化裂解,以获得通式(I)化合物。[在公式中,公式-A1-(其中前面的键表示与碳原子C1结合的键,而后面的键表示与碳原子C2结合的键)是具有2至6个碳原子的脂肪族基,可能已被取代,并且可能进一步包括醚键,酯键,次级氨基,硫醚基或这些基团,而公式-A2-(其中前面的键表示与碳原子C1结合的键,而后面的键表示与碳原子C2结合的键)是具有4至10个碳原子的脂肪族基,可能已被取代,并且可能进一步包括醚键,酯键,次级氨基,硫醚基或这些基团。]
