A fast alumina-promoted solid-phase Michael addition of enamines to conjugated enones is described under microwave irradiation in high yields. The 1,5-diketo Michael adducts have been converted into a novel class of 1′,2′-diazepino(17,16-d′) steroids.
Synthesis of a New N-Diaminophosphoryl-N'-[(2S)-2-pyrrolidinylmethyl]thiourea as a Chiral Organocatalyst for the Stereoselective Michael Addition of Cyclohexanone to Nitrostyrenes and Chalcones – Application in Cascade Processes for the Synthesis of Polyc

A highly diastereoselective and enantioselective Michael addition of enolizable ketones such as cyclohexanone and acetophenone to a variety of substituted trans-?-nitrostyrenes and chalcones was catalyzed by a novel chiral and unsymmetrical thiourea as or

(Chemical Equation Presented) Addition of cylohexanone to chalcones, obtained from the appropriate acetophenone and benzaldehyde derivatives, under solvent-free conditions gave 1,5-diketones in good yields. Treatment of 1,5-diketones with ammonium acetate in acetic acid afforded directly 2,4-diaryl-5,6,7,8-tetrahydroquinoline derivatives (7a-u) in high yields. The structures of 7a-u were elucidated by 1H NMR, 13C NMR, IR, and elemental analysis.
A mild and efficient procedure for asymmetric Michael additions of cyclohexanone to chalcones catalyzed by an amino acid ionic liquid

A mild and efficient procedure for Michael additions of cyclohexanone to chalcones has been developed. In the presence of amino acid ionic liquid [EMIm][Pro] (200 mol %), cyclohexanone reacted with various chalcones to afford Michael adducts in high yield
