Asymmetric α‐Alkylation With Activated and Unactivated Electrophiles by a Highly Productive and Recyclable Lewis Acid/Imidazolium Catalyst

open access: yesAngewandte Chemie International Edition, EarlyView.
An air‐stable, easily prepared, bifunctional Cu(II)/imidazolium complex enables highly enantioselective α‐alkylation of 1,3‐dicarbonyls with outstanding productivity (TON up to 1740). Highlights include broad electrophile scope spanning π‐activated and nonactivated reagents, stereo‐retentive allylation, simple catalyst synthesis, and efficient catalyst
