Uncatalyzed synthesis of β-enamino ketones in PEGWater

β-Enamino ketones have been synthesized in excellent yield by the reaction of aromatic or aliphatic amines with 1,3-dicarbonyl compounds in polyethylene glycol (PEG)-600water. The PEG-600 is recycled and reused. CSIRO 2008.

Metal-free syntheses of new azocinesviaaddition reactions of enaminones with acenaphthoquinone followed by oxidative cleavages of the corresponding vicinal diols

A one-pot, clean and green procedure is described for the syntheses of new azocine derivativesviaaddition reactions of enaminones with acenaphthoquinone followed by periodic acid-mediated oxidative cleavages of the corresponding vicinal diols. Various derivatives of azocine were prepared and well characterized. The excellent yields, simple synthesis procedure, lack of a need to carry out any tedious work-up and column chromatography, metal-free catalysis, and mild reaction conditions are important features of this protocol.

Silica sulfuric acid-mediated synthesis of β-enaminones and β-enaminoesters under microwave irradiation

Silica sulfuric acid, a heterogeneous reagent, has been found to be an efficient catalyst for the synthesis of β-enaminones and β-enaminoesters under microwave irradiation in a microwave reactor within 2 min. The experimental procedure is simple and environment-friendly, and results in excellent yields of the products. Further, the catalyst is recyclable, and the reaction is 60 times faster than the reaction at room temperature. Copyright Taylor & Francis Group, LLC.
