Palladium-Catalyzed Enantioselective [3 + 2] Cycloaddition of Vinylarylcyclopropanes (VACPs) with Photogenerated Ketenes to Tetrahydrofurans
{{output}}
A palladium-catalyzed asymmetric [3 + 2] cycloaddition of vinylarylcyclopropanes (VACPs) with photogenerated ketenes is disclosed. This method efficiently constructs tetrahydrofurans featuring a quaternary stereocenter with high yields and excellent enantiosel... ...
