Recent Literature


A direct asymmetric benzoyloxylation of aldehydes with benzoyl peroxide catalyzed by (S)-2-(triphenylmethyl)pyrrolidine provides optically active α-benzoyloxyaldehydes as useful chiral building blocks.

The direct asymmetric α-benzoyloxylation of β-ketocarbonyls catalyzed by a chiral primary amine demonstrates excellent enantioselectivity for a broad range of substrates, which allows convenient access to highly enantioenriched α-hydroxy-β-ketocarbonyls.

A highly regio- and enantioselective hydroxyamination of aldehydes with in situ generated nitrosocarbonyl compounds from hydroxamic acid derivatives was realized by combining TEMPO and BPO as oxidants in the presence of a binaphthyl-modified amine catalyst.

Copper-catalyzed carboamination of alkenes enables an efficient synthesis of γ-amino butyric acid (GABA) derivatives from alkenes. In this difunctionalization reaction, acetonitrile serves as the source of the carbon and nitrogen functionalities. A copper-catalyzed radical-polar crossover mechanism is proposed.

A one-pot sequential 1,3-dipolar cycloaddition/aromatization reaction sequence enables the synthesis of multisubstituted pyrroles from simple, easy available alkenes. A well-defined silver-catalyzed 1,3-dipolar cycloaddition reaction is followed by a benzoyl peroxide-mediated oxidative dehydrogenative aromatization reaction.

Photocatalysis enables the construction of 3-acyl-4-arylcoumarins in good yields from simple aldehydes and ynoates in the presence of inexpensive 2-tBu-anthraquinone as catalyst. The reaction proceeds through generation of an acyl radical intermediate, that reacts with ynoate, and then cyclization.
