Conspectus Enantiopure atropisomers have become increasingly important in asymmetric
synthesis and catalysis, pharmaceutical science, and material science since the discovery of …

Conspectus The development of highly effective chiral ligands is a key topic in enhancing
the catalytic activity and selectivity in metal-catalyzed asymmetric synthesis. Traditionally …

The asymmetric catalytic synthesis of 1, 2-diamines has received considerable interest,
especially in the last ten years, due to their presence in biologically active compounds and …

Chiral imidazolidine shows its potential in multiple fields. However, direct catalytic
asymmetric construction of chiral imidazolidines is still limited. Herein, we report an effective …

The first organocatalytic asymmetric [3+ 2]-annulation of γ-sulfonamido-α, β-unsaturated
ketones with cyclic N-sulfimines has been developed, and enantioenriched functionalized …

A Brønsted base and Lewis acid cooperatively catalyzed 1, 3-dipolar cycloaddition is
reported through chiral dinuclear zinc catalysts. An asymmetric exo′-selective [3+ 2] …

A new strategy of asymmetric carbonyl catalysis via a chiral Lewis acid-bonded aldehyde
has been developed for the direct Mannich/condensation cascade reaction of glycine ester …

The mechanism of the Cu (I)/(S, R p)-PPFOMe-catalyzed 1, 3-dipolar cycloaddition of
azomethine ylides with fluorinated aldimines has been studied using labeling experiments …

Abstract An enantioselective [3+ 2] cycloaddition of donor‐acceptor aziridines with N‐aryl
protected imines was developed with a Ni (ClO4) 2⋅ 6H2O/N, N′‐dioxide catalyst system …

Imidazolidine is a saturated heterocycle with a cyclic aminal core that can be found in
natural products and biologically active molecules. Additionally, these heterocyclic …
