Synthesis of Unsymmetrical 1,4-Dicarbonyl Compounds by Photocatalytic Oxidative Radical Additions

Herein we report a photocatalytic oxidative radical addition reaction for the synthesis of unsymmetrical 1,4-dicarbonyl compounds. This reaction utilizes a desulfurization process to generate electrophilic radicals, which add to α-halogenated alkenes and undergo further oxidation to deliver 1,4-dicarbonyl compounds. This mild and highly efficient method provides a valuable alternative to known strategies.

COMPOUND HAVING BET INHIBITORY ACTIVITY AND PREPARATION METHOD AND USE THEREFOR

The invention relates to the field of pharmaceutical chemistry. Specifically, the present invention relates to a series of BET (bromodomain and extra-terminal domain) inhibitors having a novel structure, particularly inhibitors targeting BRD4 (Bromodomain-containing protein 4), and a preparation method and use therefor. The structure thereof is shown in the following general formula (I). Said compounds or a stereoisomer, racemate, geometric isomer, tautomer, prodrug, hydrate, solvate, or crystal form thereof, or a pharmaceutically acceptable salt thereof, and the pharmaceutical compsosition thereof can be used for the treatment and/or prevention of related diseases mediated by bromodomain proteins.

Nickel-Catalyzed Transformation of Diazoacetates to Alkyl Radicals Using Alcohol as a Hydrogen Source

A nickel-catalyzed transformation of diazoacetates to α-carbonyl methylene radicals has been disclosed in the presence of hyperoxide using ethanol as a hydrogen source and solvent. This strategy is successfully applied in the formation of indolin-2-ones or 1,4-dicarbonyl compounds from acrylamides or enamides in moderate to good yields. These reactions undergo radical addition onto C-C double bonds followed by a cyclization/oxidation or an oxidation/hydrolysis process, respectively.
