Organocatalysis articles from across Nature Portfolio

Planar chiral [2.2]paracyclophanes have a wide range of applications in asymmetric synthesis and materials science. However, they are accessed via time-consuming chiral separations or kinetic resolution approaches. Here, the authors report a simple, metal-free protocol for organocatalytic desymmetrization of prochiral diformyl[2.2]paracyclophanes.

The redox properties of visible-light-absorbing photosensitizers are limited by the energy of visible photons, but methods using sensitization-initiated electron transfer have recently been developed to address these challenges. Now a multiphoton dual-catalyst strategy has been used to enable the enantioselective de Mayo reaction for the synthesis of enantioenriched 1,5-diketones.

Oil-water emulsion techniques can be used for encapsulation of chemicals and control of reactivity, but is challenging for highly reactive materials such as acids and bases. Here, the authors report the encapsulation of bases by masking of reactivity with photo-removable protecting groups.

Supramolecular confined catalysis aims to mimic the active pocket of an enzyme to enhance the efficiency and selectivity of catalytic reactions. Here, the authors describe the formation of chiral nanotubes stable in aqueous solution employing a chiral BINOL-phosphate which can accelerate the 3-aza-Cope rearrangement by a nanotubular interior confinement effect.

The photochemical properties of Electron Donor-Acceptor (EDA) complexes present exciting opportunities, but often require an inert atmosphere to maintain high efficiency. Here, the authors develop a photocatalytic system through rational design, which overcomes the oxygen-sensitive limitation of traditional EDA photocatalytic systems.

Communications Chemistry is pleased to introduce a Collection of articles focused on organomediated polymerization. Here, the Guest Editors highlight the themes within and look towards the future of this research field.

Chiral BINOL-phosphates have qualified as privileged Brønsted acid organocatalysts, providing solutions to many challenging enantioselective transformations for a wide range of substrates under mild reaction conditions. Here we revisit the story of their origins.

Stereoselective decarboxylative protonation can produce diverse chiral molecules from widely available carboxylic acids. However, general and practical strategies are lacking. Now, a chiral spirocyclic phosphoric acid-catalysed decarboxylation of aminomalonic acids has enabled the modular synthesis of α-amino acids.
