Ruthenium-catalyzed room-temperature coupling of α-keto sulfoxonium ylides and cyclopropanols for δ-diketone synthesis

Previous transition metal-catalyzed synthesis processes of δ-diketones are plagued by the high cost of the rhodium catalyst and harsh reaction conditions. Herein a low-cost, room temperature ruthenium catalytic method is developed based on the coupling of α-keto sulfoxonium ylides with cyclopropanols. The mild protocol features a broad substrate scope (47 examples) and a high product yield (up to 99%). Mechanistic studies argue against a radical pathway and support a cyclopropanol ring opening, sulfoxonium ylide-derived carbenoid formation, migratory insertion C-C bond formation pathway.

Palladium mediated one-pot synthesis of 3-aryl-cyclohexenones and 1,5-diketones from allyl alcohols and aryl ketones

One-pot synthesis of Robinson annulated 3-aryl-cyclohexenones from allyl alcohols and ketones using palladium is reported. Long chain aliphatic or aryl substitutions at the C1 position of allyl alcohol result in the formation of 1,5-diketone products. This simple one-pot method avoids the use of highly electrophilic vinyl ketones.

Photo-mediated [1, 3]-Carbonyl shift of β-Ketocarbonyls

An organic amine mediated photolytic [1,3]-benzoyl migration of β-benzoyl carbonyl compounds was reported. This migration was achieved by Norrish-Yang cyclization and retro-aldol reaction under black light (365 nm) or visible light irradiation. This photolytic protocol provides an alternative approach to the synthesis of 1,5-dicarbonyl compounds. By chiral primary amine catalysis, a kinetic resolution was also developed to afford enantioenriched 1,5-dicarbonyls.

Palladium-catalyzed cross-coupling of styrenes with aryl methyl ketones in ionic liquids: Direct access to cyclopropanes

The combined use of Pd(OAc)2, Cu(OAc)2, and dioxygen in molten tetrabutylammonium acetate (TBAA) promotes an unusual cyclopropanation reaction between aryl methyl ketones and styrenes. The process is a dehydrogenative cyclizing coupl

Generation of β-keto radicals from cyclopropanols catalyzed by AgNO3

Various β-keto radicals are generated from cyclopropanols by treatment with a catalytic amount of AgNO3 and (NH4) 2S2O8 as a reoxidant in the presence of pyridine. Thus, generated β-keto radicals react with alkenes to yield addition products. Copyright

α-arylation vs. α-arylhydrazonylation of alkyl aryl ketones with arylazo tert-butyl sulfides

Potassium enolates of alkyl aryl ketones react selectively in DMSO with phenylazo 1a and 4-methylphenylazo tert-butyl sulfide 1b undergoing respectively effective α-phenylation via S(RN)1 and α-(4-methylphenyl)hydrazonylation via elimination-addition.

Generation of β-Carbonyl Radicals from Cyclopropanol Derivatives by the Oxidation with Manganese(III) 2-Pyridinecarboxylate and Their Reactions with Electron-Rich and -Deficient Olefins

Various β-carbonyl radicals are generated oxidatively from cyclopropanol derivatives by the use of manganese(III) 2-pyridinecarboxylate (Mn(pic)3).These β-carbonyl radicals react with electron-rich olefins such as conjugated silyl enol ethers, a ketene th

Generation of β-Keto Radicals from Cyclopropanol Derivatives by the Use of Manganese(III) 2-Pyridinecarboxylate as an Oxidant and Their Reactions with Olefins

Various β-keto radicals are generated from cyclopropanol derivates such as 1- or 2-substituted cyclopropanols and a cyclopropanone hemiacetal by the use of manganese(III) 2-pyridinecarboxylate, and their reactions with electron-rich olefins give cross-addition products in good yields.

Carbanions That Function Both as Electron Transfer Agents and as Hydrogen Atom Donors: A New Electron Transfer Chain Reaction

New reactions are described in which carbanions function both as one electron transfer agents and as hydrogen atom donors; a novel feature of these reactions is the generation of a radical anion by hydrogen atom abstraction.
