Aminonitrile and cyanohydrin ethers as benzoyl anion equivalents in conjugate additions to substituted α cyclenones : comparative synthetic potentialities
Lithiated aminonitrile and cyanohydrin ether are good nucleophilic benzoyl equivalents in conjugate addition to α cyclenones. is more sensitive to β substitution of the cyclenone than , as in THF it does not react with 3-methyl substituted cyclohexenones , . From 2-methyl and 2-fluorocyclenones and or , 2-subsyituted 3-benzoylcyclanones are stereoselectively obtained, provided that mild unmasking conditions

A facile visible‐light photocatalytic conjugate addition to prepare 1,4‐dicarbonyl compounds has been developed by employing readily available aroyl chlorides as aryl radical sources. This operationally simple method shows a broad scope with regard to both aroyl chlorides and Michael acceptors. As a result, a variety of 1,4‐diketones were efficiently synthesized in moderate to good yields.
