Process for preparing conjugated diene compound utilizing intramolecular sigmatropic rearrangement reaction

Abstract

The present invention relates to A process for preparing a conjugated diene compound, the process comprising: subjecting, to an intramolecular sigmatropic rearrangement reaction, a conjugated diene compound (1) of the following general formula (1), wherein Z represents a halogen atom, a methyl group, a hydroxy group, an acetoxy group, a formyl group, or an acetal, and n and m are, independently of each other, integers of 0 to 14, or a conjugated diene compound (2) of the following general formula (2), wherein Z, n, and m are as defined above, to obtain, respectively, a conjugated diene compound (3) of the following general formula (3), wherein Z is as defined above, and n and m are, independently of each other, integers of 0 to 14, with the proviso that m−1 is an integer of zero or more, or a conjugated diene compound (4) of the following general formula (4), wherein Z is as defined above, and n and m are, independently of each other, integers of 0 to 14, with the proviso that n−1 is an integer of zero or more.
