Palladium-Catalyzed Direct 1,4-Addition of Heteroarenes to α,β-Unsaturated Ketones via C-H Activation
摘要:
Palladium-catalyzed direct conjugate additions of heteroarenes to alpha,beta-unsaturated ketones via C-H activation are described. The reactions of heteroarenes with alpha,beta-unsaturated ketones proceeded smoothly in the presence of PdCl2 as a catalyst under mild conditions to give the corresponding Michael adducts in moderate to excellent yields.
