4-oxatricyclo[4.3.1.1 3,8]undecan-5-one derivative and process for producing the same

A process for producing a 4-oxatricyclo[4.3.1.13,8]undecan-5-one derivative, comprising the step of oxidizing an adamantanone derivative shown by the following formula (2):

• wherein R is a hydrogen atom or a (meth)acryloyl group and the ring structure is optionally substituted, with molecular oxygen in the presence of an imide compound shown by the following formula (3):
• wherein each of R1 and R2 is, identical to or different from each other, a hydrogen atom, a halogen atom, an alkyl group, an aryl group, a cycloalkyl group, a hydroxyl group, an alkoxy group, a carboxyl group, an alkoxycarbonyl group, or an acyl group, where R1 and R2 may be combined to form a double bond or an aromatic or non-aromatic ring;
• X is an oxygen atom or a hydroxyl group;
• and one or two N-substituted cyclic imido groups indicated in the formula (3) may be further formed on said R1, R2, or on the double bond or aromatic or non-aromatic ring formed together by R1 and R2, and in the coexistence of an co-oxidizing agent to yield a 4-oxatricyclo[4.3.1.13,8]undecan-5-one derivative shown by the following formula (1):
• wherein R is a hydrogen atom or a (meth)acryloyl group and the ring structure is optionally substituted.
