  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.

  先前的技术要求使用专门的基质或反应条件来制造多取代环丁烷化合物和多取代环丁烯化合物，该方法的普适性较差。在工业生产多取代环丁烷化合物时，所使用的催化剂或溶剂的类型或数量也存在问题。本发明提供了一种制造高立体选择性、环境负荷低（具有生态优势）且从操作、基质普适性、催化剂、溶剂和效率的角度适用于工业生产的多取代环丁烷化合物的方法。通过使Brønsted酸作用于烯醚化合物或2-硅氧基二烯化合物与烯烃或炔烃化合物的混合物，其中在1位取代了羰基基团，可以在非水溶剂或无溶剂的情况下高效、立体选择性地、具有生态优势地制造多取代环丁烷、环丁烯和双环[4.2.0]辛烷化合物。
