Tandem three-component reactions of aldehyde, alkyl acrylate, and dialkylmalonate catalyzed by ethyl diphenylphosphine.
A new highly efficient three-component reaction of alkyl acrylate, aldehyde and dialkyl malonate using ethyl diphenylphosphine as organocatalyst has been described. Various highly functional compounds bearing hydroxyl groups and the ester functions can be easily prepared in moderate to good yields according to our one-step procedure. The reactions are believed to proceed via Morita-Baylis-Hillm...
متن کاملOrganocatalytic tandem three-component reaction of aldehyde, alkyl vinyl ketone, and amide: one-pot syntheses of highly functional alkenes.
An EtPPh(2)- or PPh(3)-catalyzed tandem three-component reaction of aldehyde, alkyl vinyl ketone, and amide is developed. Its further application in one-pot syntheses of highly functional alkenes starting from aldehydes, alkyl vinyl ketones, and amides is realized. A wide variety of highly functional α,β-unsaturated ketones can be furnished in 68-99% yields with high stereoselectivity (E/Z up t...
متن کاملAn Efficient Synthesis of Benzylamino Coumarin Derivatives via Three-component Coupling of 4-hydroxycoumarin, Aromatic Aldehyde and Cyclic Secondary Amine Catalyzed by CuO Nanoparticles
A green and efficient one-pot synthesis of benzylamino coumarin derivatives was conducted by a three-component condensation of 4-hydroxycoumarin, cyclic secondary amine, and aromatic aldehyde in the presence of CuO nanoparticles (NPs) as a heterogeneous catalyst in water at room temperature.
متن کاملMechanistic insights into nickamine-catalyzed alkyl-alkyl cross-coupling reactions.
Within the last decades the transition metal-catalyzed cross-coupling of non-activated alkyl halides has significantly progressed. Within the context of alkyl-alkyl cross-coupling, first row transition metals spanning from iron, over cobalt, nickel, to copper have been successfully applied to catalyze this difficult reaction. The mechanistic understanding of these reactions is still in its infa...
متن کاملSynthesis of alkyl 2-(4-oxoquinazolin-3(4H)-yl) acrylate by nucleophilic additionof alkyl propiolates catalysed by Ph3P
4-Hydroxyquinazoline undergoes neutral conditions with alkyl propiolates in the presence of triphenylphosphine (0.26g), and by α substituation the corresponding 2-(4-oxoquinazolin-3(4H)-yl acrylate was obtained in good yields.
