Modular Synthesis of Densely Functionalized Azetidines: Ni-Catalyzed 1,4-Alkylarylation of 1,3-Enynes with 1-Azabicyclo[1.1.0]butanes through Polar-Radical Relay
{{output}}
An efficient synthesis of densely functionalized azetidines has been achieved via a Ni-catalyzed 1,4-alkylarylation of 1,3-enynes using 1-azabicyclo[1.1.0]butanes (ABBs) and arylboronic acids. This three-component reaction offers an easy way to incorporate an ... ...
