The prior art required specialized substrates or reaction conditions to be used to manufacture polysubstituted cyclobutane compounds and polysubstituted cyclobutene compounds, and the method had poor generality. The type or quantity of the catalyst or solvent used was also problematic in the industrial manufacture of polysubstituted cyclobutane compounds. The present invention provides a method for manufacturing a polysubstituted cyclobutane compound with high stereoselectivity that has low environmental load (is ecologically advantageous) and is applicable to industrial manufacturing from the standpoint of operation, substrate generality, catalyst, solvent, and efficiency. A polysubstituted cyclobutane, a cyclobutene, and a bicyclo[4.2.0]octane compound can be manufactured efficiently, stereoselectively, and in an ecologically advantageous manner by causing a Brønsted acid to act on a mixture of an enol ether compound or 2-siloxydiene compound with an alkene or alkyne compound in which a carbonyl group is substituted at the 1-position in a non-aqueous solvent or without a solvent.
