Highly efficient acetalization of carbonyl compounds catalyzed by anilin-aldehyde resin salts

A mild procedures for the syntheses of ethylene acetals and dimethyl acetals from the corresponding aldehydes and ketones catalyzed by 1mol% of anilinealdehyde resin salts are described. This method is also useful for the synthesis of dimethyl acetals of diaryl ketones.

REAGENT FOR ENHANCING GENERATION OF CHEMICAL SPECIES

Described is a reagent that enhances acid generation of a photoacid generator and a composition containing such a reagent.

Synthesis of D-erythro-sphinganine through serine-derived α-amino epoxides

A total synthesis of d-erythro-sphinganine [(2S,3R)-2-aminooctadecane-1,3- diol] starting from commercial N-tert-butyloxycarbonyl-l-serine methyl ester is described. The approach is based on the completely stereoselective preparation of an α-amino epoxide obtained by treating a protected l-serinal derivative with dimethylsulfoxonium methylide. The oxirane synthon is obtained with an anti configuration fitting the (2S,3R) stereochemistry of the 2-amino-1,3-diol polar head of d-erythro-sphinganine. The synthetic procedure afforded the target compound in a 68% overall yield based on the initial amount of the starting l-serine material.

Anodic cleavage of several ketone N-phenylsemicarbazones into methyl N-phenylcarbamate and the corresponding dimethyl acetals

Several ketone N-phenylsemicarbazones were electrooxidized in the presence of potassium iodide and a base using methanol as the solvent to give nearly commensurate amounts of methyl N-phenylcarbamate and the corresponding dimethyl acetals. Continuous evolution of gaseous nitrogen was observed from the anolyte during the electrooxidation. The reactions were carried out under very mild reaction conditions and are presumed to proceed through a four-electron oxidation process, in which the iodide ion plays an important role as an electron carrier.

An efficient method for conversion of ketones to their corresponding dimethyl and diethyl acetals and of cyclic β-diketones into β-keto enol ethers using Fe(OTs)3 as a catalyst is described. Copyright Taylor & Francis Group, LLC.

A simple method for conversion of ketones to their corresponding dimethyl acetals using montmorillonite K 10 and p-toluenesulfonic acid as acidic cocatalysts under very mild reaction conditions is described. Copyright Taylor & Francis Group, LLC.

A simple and versatile method for the synthesis of acetals from aldehydes and ketones using bismuth triflate

Acetals are obtained in good yields by treatment of aldehydes and ketones with trialkyl orthoformate and the corresponding alcohol in the presence of 0.1 mol % Bi(OTf)3·4H2O. A simple procedure for the formation of acetals of diaryl ketones has also been developed. The conversion of carbonyl compounds to the corresponding 1,3-dioxolane using ethylene glycol is also catalyzed by Bi(OTf)3· 4H2O (1 mol %). Two methods, both of which avoid the use of benzene, have been developed.

An Improved Procedure for the Preparation of Acetals from Diaryl Ketones

Acetals of diaryl ketones with nitro, halo and methoxy substituents are easily prepared in high yield by treatment with an alcohol and the corresponding trialkyl ortoformate in the presence of catalytic amount of trifluoromethanesulfonic acid.

Electrochemical Oxidation of Benzophenone Hydrazones

The anodic oxidation of benzophenone hydrazones (1) was found to give several products, depending upon the electrolysis conditions employed such as electrode material, temperature, and electrolyte composition.For example, the oxidation using a platinum anode at room temperature in LiClO4-MeCN afforded exclusively benzophenone azines (2), whereas in NaOMe-MeOH benzophenone dimethyl acetals (3) were formed as the main products.On the other hand, the oxidation using a graphite anode in refluxing MeOH containing NaOMe gave diphenylmethyl methyl ethers (4), along with diphenylmethanes (5).When the analogous electrolysis was conducted in the presence of methacrylic acid derivatives, corresponding diphenylcyclopropanes (7) were obtained in relatively high yields.
