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.

二芳基取代的环戊二烯的高度立体选择性直接构建†
已经开发出了铜催化的立体选择性[2 + 2]环化反应，为直接构建二芳基取代的环丁烷提供了简洁的方案，产率高达99％，大于95/5 dr。同时，该反应的对映选择性也得到了实现，从而产生了一系列光学活性高达94％ee的旋光性二芳基取代的环丁烷。
