A copper(I)/DDQ-mediated double-dehydrogenative Diels-Alder (DDDA) reaction of simple butenes with 1,4-diketones and indolones has been established for the first time. This strategy is based on a tandem double-dehydrogenation/Diels-Alder reaction from nonprefunctionalized starting materials, in which both a diene and dienophile were in situ generated via activation of fourfold inert C(sp3)-H bonds in one catalytic system.

An efficient one-pot synthesis of O-heterocycles or aryl ketones has been achieved using Et3SiH in the presence of InCl3 via a sequential ionic hydrogenation reaction by switching the solvent. This methodology can be used to construct C-O bonds and to prepare conjugate reduction products, including chromans, tetrahydrofurans, tetrahydropyrans, dihydroisobenzofurans, dihydrochalcones, and 1,4-diones in a facile manner. In addition, a novel plausible mechanism involving a conjugate reduction and a tandem reductive cyclization was verified by experimental investigations.

1,4-Diketones have been synthesized via a reductive homocoupling of α-haloketones. Addition of a Grignard reagent to titanium(IV) isopropoxide affords a low-valent titanium(III) intermediate that is believed to mediate a radical dimerization reaction. The

A new facile method for the synthesis of β-keto sulfones employing xanthates, DMSO, and Fenton's reagent is described. The reaction proceeds under very mild conditions providing a cost-effective straightforward approach to various β-keto sulfones in high yields.

Malaria is one of the most significant tropical diseases and remains a major challenge due to the lack of a broadly effective vaccine and parasite resistance to current drugs. This means there is a need for new drug candidates with novel modes of action.
A simple method for the synthesis of furfuryl ketones and furylacetic acid derivatives
Chalikidi, Petrakis N.,Nevolina, Tatyana A.,Uchuskin, Maxim G.,Abaev, Vladimir T.,Butin, Alexander V.
, p. 621 - 629 (2015/10/12)
A simple preparative method has been developed for the synthesis of aryl(furfuryl) ketones, amides, and furylacetic acid esters, based on radical alkylation of furan derivatives at the α-position with O-ethyl(phenacyl)xanthogenates and phenacyl iodides in the presence of Fenton's reagent (H2O2/FeSO4·7H2O) in DMSO. The range of applicability and mechanisms for the formation of major and side products have been considered.

A novel method for the synthesis of 1,4-diketones from β-ketosulfones was developed by means of a visible light-induced Ci£S bond activation process. Symmetrical and unsymmetrical 1,4-diketones can be easily prepared in moderate to good yields. A new and efficient method for the synthesis of 1,4-diketones from β-ketosulfones was developed by means of a visible-light-induced Ci£S bond activation process (see scheme). Symmetrical and unsymmetrical 1,4-diketones can be easily prepared in moderate to good yields.

Polypyrrole stabilised palladium nanoparticles show good catalytic efficiency for the chemoselective transfer hydrogenation of α,β- unsaturated carbonyl compounds. The catalyst is very specific and selectively hydrogenates the olefins or acetylenes only,
