Autoinductive Effects in Zinc‐Catalyzed Alkylations of Benzaldehyde Mediated by Simple Chiral β‐Amino Alcohol Ligands

ChemistryEurope, EarlyView.
The first report on zinc‐catalyzed enantioselective alkylation of aldehydes mediated by a chiral auxiliary is revisited, and the studies show much more complex behavior than previously thought. Studies show an enantiodivergence of the reaction as a function of its progress, due to an autoinduction phenomenon.

Multiple Atropo Selectivity by κ2‐N,O‐Oxazoline Urea Ligands in Cobaltaelectro‐Catalyzed C─H Activations: Decoding Selectivity with Data Science Integration

ChemistryEurope, EarlyView.
Cobaltaelectro‐catalyzed C─H activation enables simultaneous construction of indoles with up to two distinct C─N chiral axes. High stereoselectivity derives from newly developed chiral κ2‐N,O‐oxazoline urea ligands. Multivariate linear regression modeling reveals ligand–substrate features affecting the second C─N chiral axis, and density functional ...

Stereodynamism in chiral polyaromatic phosphepines

Chemistry – A European Journal, Accepted Article.
In the present experimental‐computational study, we demonstrate that the stereodynamism of phosphahelicenoid can be used to afford diastereoisomers of polyaromatics fused with a chiral phosphepine (7‐membered P‐ring). In particular, we highlight a complex interplay between the inversion at the P centre and helicenoid epimerization as well as a ...
