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.

Paragraph 0157-0159, (2020/12/22)
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.

Chemical transformations that install heteroatoms into C?H bonds are of significant interest because they streamline the construction of value-added small molecules. Direct C?H oxyfunctionalization, or the one step conversion of a C?H bond to a C?O bond, could be a highly enabling transformation due to the prevalence of the resulting enantioenriched alcohols in pharmaceuticals and natural products,. Here we report a single-flask photoredox/enzymatic process for direct C?H hydroxylation that proceeds with broad reactivity, chemoselectivity and enantioselectivity. This unified strategy advances general photoredox and enzymatic catalysis synergy and enables chemoenzymatic processes for powerful and selective oxidative transformations.
