Bifunctional Photocatalysts: Exploiting Proximity for Enhanced Reaction Performance
This review covers the application of the bifunctional approach to photocatalysis as a means to attain (enhanced) enantioselectivity, and, more in general, as a strategy to enhance the catalytic performance through an effective use of short‐lived reaction intermediates.

An iridium‐catalyzed linear‐selective sp3 C─H alkylation of N‐methylamides with alkenes is described. This method tolerates various N‐methylacetamide derivatives and has a broad alkene scope. Mechanistic studies were also conducted. Internal alkenes can also be used through in situ consecutive alkene isomerization.

Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

This review highlights biocatalytic prenylation as a versatile strategy for tailoring the functional properties of peptides and proteins. By comparing branched isoprenoids with linear lipids, we illustrate how specific prenyl architectures modulate the behaviors of lipidated proteins within membrane environments.

Alkali‐Metal Base Catalyzed Electrocyclization of Isoprene Derivatives
Simple and abundant alkali‐metal base catalysis in combination with Lewis basic polyamines enables the electrocyclization of isoprene‐derived trienes to cycloheptadienes under neat conditions. Mechanistic insight supported by DFT guides a scalable route to seven‐membered carbocycles which, after reduction, give saturated cycloalkanes relevant as ...
