TL;DR: The new bidentate oxazoline-carbene precursor with planar and central chirality had significant advantage than the bicyclic 1,2,4-triazolium salt derived from [2.2]paracyclophane as a monodentate carbene ligand in Cu(I)-catalyzed asymmetric β-boration of α,β-unsaturated esters, giving the desired products in high enantioselectivities and yields.

TL;DR: The dual chiral carbene-copper catalyst has significant advantages over its carbene counterpart as an organocatalyst in asymmetric β-boration of acyclic enones, giving a variety of chiral β-boryl ketones in good yields and enantioselectivities.

TL;DR: In this article, a chiral carbene-copper catalyst has been successfully synthesized and applied to enantioselective α-silylations of N-tosylaldimines.

TL;DR: In this article, a successful development had been achieved in the asymmetric 1,2-addition of arylboronic acids to aromatic aldehydes by the use of macrocyclic planar chiral NHC-Rh complexes derived from [2.2]paracyclophane.

TL;DR: In this paper, a planar chiral carbene-copper complexes based on the [2.2]paracyclophane backbone with a pseudo-ortho substitution pattern were synthesized and applied to asymmetric β-boration of α,β-unsaturated esters.
