PROCESS FOR PREPARING 3-PHENYLCYCLOHEXANONE AND DERIVATIVES THEREOF

Claims

The present invention provides a novel process for preparing a 3-phenylcyclohexenone compound having one or more substituents at position 6 and a novel process for preparing derivatives of a 3-hydroxybiphenyl compound having one or more substituents at position 4 using the same compound. Furthermore, the present invention provides a process for preparing a compound represented by formula (3), comprising a step in which a compound represented by formula (1) (where R1, R2, R3, R4, and R5 are identical or different from each other and each represent a hydrogen atom and the like, R6 represents a C1-C6 hydrocarbon chain group that may optionally be substituted with a phenyl group, R7 represents a hydrogen atom and the like, or alternatively, R6 and R7 may combine to form -(CH2)4- and the like) or salts thereof,A compound represented by formula (2) (where R8 represents a C1-C12 chain hydrocarbon group and R9 represents a hydrogen atom and the like) and an alkali metal carbonate are mixed and then reacted in the presence of a pyrrolidine to obtain the compound represented by formula (3) (where R1, R2, R3, R4, R5, R8 and R9 are the same as those defined above).
