Nickel-Catalyzed Reductive Cross-Coupling of Aryl Bromides with Vinyl Acetate in Dimethyl Isosorbide as a Sustainable Solvent

A nickel-catalyzed reductive cross-coupling has been achieved using (hetero)aryl bromides and vinyl acetate as the coupling partners. This mild, applicable method provides a reliable access to a variety of vinyl arenes, heteroarenes, and benzoheterocycles, which should expand the chemical space of precursors to fine chemicals and polymers. Importantly, a sustainable solvent, dimethyl isosorbide, is used, making this protocol more attractive from the point of view of green chemistry.

Highly selective electroreductive linear dimerization of electron-deficient vinylarenes

A direct electroreductive dimerization of electron-deficient vinylarenes for the synthesis of 1,4-diarylbutane has been developed using a simple undivided cell with inexpensive carbon electrodes at room temperature. The control and deuterium-labeling experiments of electroreductive dimerization suggest that the hydrogen source comes from the solvent CH3CN. This protocol provides a mild and efficient route for the construction of C–C bond in moderate to good yields with high regioselectivity and broad substrate scope.

Preparation method of novel isobenzofuranone intermediate

The invention discloses a synthetic method of an important intermediate of novel diuretic drug ROMK inhibitor. The synthetic method comprises the following steps: adopting 4-nitro phthalimide as the starting material, performing two-step reaction, diazotization reaction, Suzuki reaction and epoxidation reaction, thus obtaining the important intermediate 5-epoxy ethyl isobenzofuranone of the ROMK inhibitor. The preparation method provided by the invention is mild in route reaction conditions, simple in after-treatment, high in yield, and capable of avoiding the use of toxic gases and bioenzymecatalysts.
