Three-dimensional aliphatic fused and bridged rings are key pharmacophores in drugs and bioactive natural products. Here, we reported an organocatalytic visible-light induced dearomative cycloaddition of (hetero)arenes, with organic light-emitting diode material 4CzIPN or readily accessible thioxanthone as photocatalyst. A series of cyclobutane-fused polycyclic structures and bridgedbicyclo scaffolds were prepared
Amidation of Aldehydes and Alcohols through α-Iminonitriles and a Sequential Oxidative Three-Component Strecker Reaction/Thio-Michael Addition/Alumina-Promoted Hydrolysis Process to Access β-Mercaptoamides from Aldehydes, Amines, and Thiols
hydrolysis conditions for converting α‐iminonitriles into carboxamides have been developed. In combination with the oxidative three‐component Strecker reaction, the one‐pot direct amidation of aldehydes and alcohols is reported. Subsequently, an Yb(OTf)3‐catalyzed Michael addition of thiols to α,β‐unsaturated α‐iminonitriles is reported for the synthesis of β‐mercapto‐α‐iminonitriles. The successful integration

We synthesized a single-atom iron catalyst (Fe-SA@NC), which exhibits good conversion efficiency in organic electro oxidation as an advanced redox mediator. This study provides valuable insights into the design of catalytic systems for organic tandem reactions from an inorganic chemistry aspect.
