Abstract
Provided is a method with which an α-allylated cycloalkanone is obtained from a macroyclic compound used as a starting material. The method is a method for producing an α-allylated cycloalkanone represented by General Formula (IV), and the method includes a step of reacting a compound represented by General Formula (I) and/or a compound represented by General Formula (II) with a compound represented by General Formula (III) in the presence of an acid catalyst to produce an α-allylated cycloalkanone represented by General Formula (IV), the acid catalyst including an acid catalyst that includes an ammonium cation and an anion. where R, R, and Rare the same or different and each of them is an alky group having 1 or mom and 4 or less of carbon atoms, the group -A- (it should be noted that the front bond refers to a bond that binds to the carbon atom Cand the back bond refers to a bond that binds to the carbon atom C) is an alkylene group having 4 or more and 20 or les of carbon atoms that optionally contains a hetero atom and optionally has a substituent, and Ris a hydrogen atom or an alkyl group having 1 or more and 4 or less of carbon atoms.
