Summary of main observation and conclusion A copper catalyzed stereoselective [2+2] cyclization has been developed, providing a concise protocol to the direct construction of diaryl‐substituted cyclobutanes in up to 99% yield with up to >95/5 dr. Meanwhile, the enantioselective version of this reaction has also been achieved, leading to a series of optically active diaryl‐substituted cyclobutanes with up to 94% ee.
