Enantioselective [2+2] cycloaddition reaction of azabenzonorbornadienes and oxabenzonorbornadienes with internal alkynes has been enabled by a catalyst system comprising Ni(COD) and (R)-SIPHOS-Ph-Mor. This transformation represents the first asymmetric [2+2] cycloaddition reaction of azabenzonorbornadienes with internal alkynes, providing a straightforward method to prepare four-membered carbocycles.
氮杂苯并降蒈二烯和氧杂苯并降蒈二烯与内部炔烃的对映选择性[2+2]环加成反应可以通过包含 Ni(COD)和(R)-SIPHOS-Ph-Mor 的催化剂体系来实现。这种转化代表了氮杂苯并降蒈二烯与内部炔烃的首例不对称[2+2]环加成反应，为制备四元碳环提供了一种直接的方法。
