Asymmetric Reduction of Unactivated Alkenes

open access: yesChemistry – A European Journal, EarlyView.
Unactivated alkenes rank among the most inert functional groups in synthesis and their selective reduction remains challenging. This Review charts the evolution from classical metal‐catalyzed hydrogenation to radical hydrogen atom transfer (HAT) and emerging biocatalytic concepts, highlighting how complementary mechanistic strategies, including the ...

Bifunctional Photocatalysts: Exploiting Proximity for Enhanced Reaction Performance

open access: yesChemistry – A European Journal, EarlyView.
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.
