20220153671 · 2022-05-19 · ·

Provided is a method with which an α-allylated cycloalkanone is obtained from a cyclic compound cycloalkanone used as a starting material. The method is a method for producing an α-allylated cycloalkanone represented by General Formula (III), and the method includes: a step 1: reacting a compound represented by General Formula (I) and alcohol having 1 or more and 4 or less of carbon atoms in the presence of a first acid catalyst and optionally a dehydrating agent; and a step 2: reacting a crude product obtained in the step 1 and a compound represented by General Formula (II) in the presence of a second acid catalyst to produce an α-allylated cycloalkanone represented by General Formula (III). The step 1 and the step 2 are consecutively performed. In the formulae above, the group -A.sup.1- (it should be noted that the front bond refers to a bond that binds to the carbon atom C.sup.1 and the back bond refers to a bond that binds to the carbon atom C.sup.2) is an alkylene group having 4 or more and 20 or less of carbon atoms that optionally contains a hetero atom and optionally has a substituent, and R.sup.4 is a hydrogen atom or an alkyl group having 1 or more and 4 or less of carbon atoms.
