摘要:
A Ni-catalyzed enantioselective reductive three-component alkylalkenylation of beta,gamma-alkenyl ketones with cis-alkenyl iodides and fluoroalkyl iodides in the presence of Mn is reported. By leveraging five-membered nickellacycles stabilized by pendant ketone group and chiral bis(oxazoline) (BiOx) ligand, this three-component protocol allows efficient access to enantioenriched beta-alkenyl ketones from simple starting materials. Ni-catalyzed three-component alkylalkenylation of diverse electronically unbiased alkenes beyond beta,gamma-alkenyl ketones that enables regioselective construction of two C(sp(3))-C(sp(3)) and C(sp(3))-(sp(2)) bonds in one single operation is also demonstrated.
