A Facile and Efficient Synthesis of Six-Membered Enol Carbocyclic Compounds

A facile and efficient method for the synthesis of six-membered enol carbocyclic compounds was realized by intermolecular cyclization reaction of 3-aryllidenepentane-2,4-diones with t-BuOK in CH2Cl2. The reaction is conducted under m

Amine-catalyzed direct self Diels-Alder reactions of α,β-unsaturated ketones in water: Synthesis of pro-chiral cyclohexanones

Amine-catalyzed direct self Diels-Alder reactions of α,β-unsaturated ketones have been developed. (S)-1-(2-Pyrrolidinyl-methyl)pyrrolidine, L-proline and pyrrolidine catalyzed the reaction of α,β-unsaturated ketones to provide cyclohexanone derivatives with good yield (up to 80%) in a single step via in situ-generation of 2-amino-1,3-butadienes and iminium ion-activated enones. Pro-chiral cyclohexanones were selectively prepared with pyrrolidine catalysis in water.

Cyclodimerization of α,β-unsaturated ketones catalyzed by lanthanoid tri-2-propoxides

α,β-unsaturated ketones are cyclodimerized by the catalysis of lanthanoid tri-2-propoxides into substituted cycohexanones in good yields. The catalytic activity of the lanthanoids is fairly superior to those of the sodium or aluminum propoxides.

Michael Addition of Acyclic Lithium 1,3-Dien-2-olates with α,β-Unsaturated Esters, Ketones, and Diesters

The Michael addition of lithium 1,3-dien-2-olates with α,β-unsaturated carbonyl compounds is described.With α,β-unsaturated esters the reaction was reversible even at -78 deg C, while kinetically controlled with α,β-unsaturated ketones or alkylidenemalona

The Double Michael Reaction of α,β-Unsaturated Ketones with Siloxydienes Catalyzed by Trityl Perchlorate Forming Six-Membered Ring Systems

In the presence of a catalytic amount of trityl perchlorate, the double Michael reaction of α,β-unsaturated ketones with siloxydienes smoothly proceeds to afford six-membered ring systems stereoselectively in good yields.Decalin derivatives are also obtai

Cyclodimerizations of Alkyl Styryl Ketones and Their Silyl Enol Ethers by Use of Iron Carbonyls

The reaction of alkyl styryl ketones with Fe3(CO)12 gives 3-acyl-4,5-diphenylcyclohexanones in a manner of cyclodimerization. (η4-Enone)Fe(CO)3 complexes serve as catalyst for this reaction.Silyl enol ethers of the same ketones afford 4-a

REACTIONS WITH LITHIUM DIMETHYLCUPRATE AND LITHIUM DIMETHYLAURATE. SOLVENT EFFECTS ON THE CONJUGATE ADDITION.

The reaction of lithium dimethylcuprate with E-4-phenyl-3-buten-2-one in different solvents has been investigated.Fast conjugate addition occurs in hydrocarbons, dichloromethane and diethylether, while the reaction is retarded in better coordinating solvents.In highly polar solvents such as DMF or DMSO, no conjugate addition is observed.Dichloromethane-d2 was chosen as a convenient solvent for NMR investigations of cuprates.The reaction of lithium dimethylaurate with different enones gave no conjugate addition products, but base induced self-condensation of enones.
