Herein, we report a photocatalytic strategy for the C−H functionalization of saturated azaheterocycles under mild conditions with only one equivalent of starting material. Our strategy is based on a redox active benzamide protecting group that is activated via a halogen‐atom transfer (XAT) process to trigger the formation of an α‐amino radical. This nucleophilic radical intermediate was then engaged in Giese additions and radical cross couplings to afford C−H alkylated and arylated products. [ABSTRACT FROM AUTHOR]

Transition metal‐catalyzed, C−C and C−N bond‐forming reactions have made an enormous impact in the way complex molecules are assembled. The benefits of solid‐phase chemistry soon made this type of reaction applicable to solid‐supported processes. In this review, we report the most recent applications and possibilities of this combination. Remarkably, the solid‐phase CuAAC and ring‐closing metathesis have demonstrated an important role in synthetic biology, alike more traditional Pd‐catalyzed reactions, such as Suzuki‐Miyaura, Heck, Sonogashira, which are valuable tools for accessing libraries of biologically relevant small molecules. Examples proved the validity of solid‐phase transition metal‐catalyzed reactions as a practical and fast strategy to cover the current organic chemistry demands. [ABSTRACT FROM AUTHOR]

An efficient and novel synthetic strategy for the generation of different carbocyclic moieties by ring closing carbonyl-olefin metathesis is reported. Herein, we describe a sustainably attractive protocol for one of the most powerful carbon-carbon bond-forming reactions, based on solvent-reduction, use of InCl 3 catalyst, and microwave irradiation, affording target compounds with yields up to 96%.
