Abstract:

β-Enaminone derivatives are useful synthetic precursors. β- N-Substituted ( E)-enaminones and β-N-substituted ( E)-aminoacrylates were synthesised with high regio- and stereo-selectivity via using the co-catalytic system of FeCl3/PTSA, which also provides a new way to the formation of C–O bond.

Abstract:

The reaction of isodehydracetic acid with amines was serendipitously found to afford β-enaminones in the presence of the coupling agent 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDC). Under the optimal reaction condition, 23 examples of α-aminomethylene glutaconic anhydride were obtained at approximately 30−80% yields. This is a concise, operationally simple method to expediently synthesize a new type of β-enaminone-containing compound.

Abstract:

As they include both nucleophilic and electrophilic moieties on the same skeleton, enaminones are an important subclass of chemical compounds that contain conjugated NC=C-C=O fragments. These active sites aid in the production of organic molecules containing linear or cyclic heteroatoms. Enaminones and the chemica1 compounds produced from them are both biologically active against the most dangerous bacteria. As a result, they have been utilized as starting materials for the synthesis of anti-inf1ammatory, antibacteria1, anticonvulsant, anticancer, anti-urease, anti-malaria1, optically luminesc

A total of 24 novel organocatalysts based on (S)-quininamine as a chiral tertiary amine and on enaminone or 1,2-benzenediamine as hydrogen bond donors were synthesized. The enaminone-type catalysts were prepared by the transamination of N,N-dimethyl enaminones with (S)-quininamine (9 examples) and the 1,2-benzenediamine-type catalysts were prepared in 3 steps from (S)-quininamine and ortho-fluoronitrobenzene derivatives (15 examples). Their organocatalytic activity was evaluated in the Michael addition of acetylacetone to trans-β-nitrostyrene. Enantioselectivities of up to 72% ee were observed

Abstract:

A simple and general one-pot method for the synthesis of spiro-2H-pyrroles has been developed. Initially, cyclohexane-embedded β-enaminones with internal alkyne functionality were synthesized by conjugate addition of 1-ethynylcyclohexylamine to α,β-alkynic ketones, followed by palladium-catalyzed coupling of the resulting N-propargylic β-enaminones with aryl iodides. When subjected to basic conditions, the cyclohexane-embedded β-enaminones with internal alkyne functionality underwent tandem nucleophilic cyclization and benzylic C–H oxidation to furnish 3,4-diaryloyl-1-azaspiro[4.5]deca-1,3-die

Abstract:

Aim and Objective: Citrus Juice as an efficient, cost-effective and green catalyst employed for one-pot synthesis of various β-substituted enaminones through the reaction of β- dicarbonyl compounds with different primary amines in a solvent-free conditions on silica gel as solid surface using grindstone technique in high yields and short reaction times. The presented procedure is operationally simple, practical and green. Material and Methods: The wide application of this procedure is demonstrated by the use of various substituted amines to react with β-dicarbonyl compounds. The method was suc
