AbstractA simple and facile synthesis of β-amino carbonyl compounds was developed by the one-pot condensation of cyclohexanone, aromatic aldehydes and anilines at 25°C in the presence of silica supported phenylphosphinic acid. β-Amino carbonyl compounds were obtained in moderate to good yields and reasonable diastereoselectivities. This method has the advantages of short reaction time, mild reaction conditions, reusable catalyst, cost efficiency and environment friendly. In addition, acetophenone and aliphatic ketones as reactants were investigated.

The elimination of volatile organic solvents in organic synthesis is the most important goal in “Green” chemistry. We report a simple, efficient and facile method for the addition of progargyl bromide to carbonyl compounds using Mg metal as a mediator under solvent-free conditions which could regioselectively generate homopropargyl alcohols efficiently in good to excellent yields. The procedure has advantages such as short reaction time, operationally simple, excellent product yields, high regioselectivity and organic solvent-free.
