Screening for generality in asymmetric catalysis. [PDF]

open access: yesNature, 2022
Research in the field of asymmetric catalysis over the past half century has resulted in landmark advances, enabling the efficient synthesis of chiral building blocks, pharmaceuticals, and natural products. A small number of asymmetric catalytic reactions have been identified that display high selectivity across a broad scope of substrates; not ...

Holistic prediction of enantioselectivity in asymmetric catalysis. [PDF]

open access: yesNature, 2019
When faced with unfamiliar reaction space, synthetic chemists typically apply the reported conditions (reagents, catalyst, solvent and additives) of a successful reaction to a desired, closely related reaction using a new substrate type. Unfortunately, this approach often fails owing to subtle differences in reaction requirements.

Asymmetric catalysis mediated by a mirror symmetry-broken helical nanoribbon [PDF]

open access: yesNature Communications, 2019
If asymmetric catalysts were available by mirror symmetry breaking, an important insight may be given to how the biomolecular homochirality emerged in nature. Here, the authors report the first example of asymmetric catalysis by employing mirror symmetry-

Electricity-driven asymmetric bromocyclization enabled by chiral phosphate anion phase-transfer catalysis

open access: yesNature Communications, 2023
Asymmetric electrochemical synthesis via ion-pairing catalysis is challenging due to interference of the electrolyte with the ion-pairing catalyst.

Ferrocene-derived P,N ligands: synthesis and application in enantioselective catalysis [PDF]

open access: yesGreen Processing and Synthesis, 2013
Due to their unique steric and electronic properties, air-stability and modular structure, chiral hybrid P,N-ferrocenyl ligands play a prominent role in the field of asymmetric catalysis.

Asymmetric Ion‐Pairing Catalysis [PDF]

open access: yesAngewandte Chemie International Edition, 2012
AbstractCharged intermediates and reagents are ubiquitous in organic transformations. The interaction of these ionic species with chiral neutral, anionic, or cationic small molecules has emerged as a powerful strategy for catalytic, enantioselective synthesis.

Heterobifunctional Rotaxanes for Asymmetric Catalysis. [PDF]

open access: yesAngew Chem Int Ed Engl, 2020
AbstractHeterobifunctional rotaxanes serve as efficient catalysts for the addition of malonates to Michael acceptors. We report a series of four different heterobifunctional rotaxanes, featuring an amine‐based thread and a chiral 1,1′‐binaphthyl‐phosphoric‐acid‐based macrocycle.
