Regioselective Oxidative Oligomerization of 2‐Tert‐Butylpyrene Toward Structurally Defined Oligomers and Their Application in Organic Light‐Emitting Diodes

European Journal of Organic Chemistry, EarlyView.
Treatment of 2‐tert‐butylpyrene with Cu2+ afforded structurally well‐defined pyrene oligomers, up to the 13‐mer. Single‐crystal X‐ray diffraction, spectroscopic analyses, and computational studies were conducted to evaluate the properties of the resulting oligopyrenes.

Competing Charge Transport Pathways: A Spirobifluorene‐Based Molecular Loop

European Journal of Organic Chemistry, EarlyView.
A rigid molecular loop integrating a spirobifluorene (SBF) core with a cycloparaphenylene (CPP) moiety provides two distinct transport channels. Through‐space spiroconjugation and radial π‐conjugation along a CPP backbone coexist within a single molecule.

A Straightforward Synthesis of Benzestrol by Matteson Homologation Using Chiral Benzyl Carbamates

European Journal of Organic Chemistry, EarlyView.
Benzestrol can easily be obtained stereoselectively via Matteson reaction using chiral Boronic esters and chiral benzyl carbamates. A straightforward and highly stereoselective synthesis of the non‐steroidal estrogen benzestrol is described based on Matteson homologations.

Protein‐Based High‐Performance Liquid Chromatography and Cyclodextrin‐Capillary Electrokinetic Chromatography for the Chiral Separation of Azoles

ELECTROPHORESIS, EarlyView.
Human serum albumin‐based high‐performance liquid chromatography and cyclodextrin‐based capillary electrokinetic chromatography were used for the chiral separation of azoles. Although only two of the five tested azoles could be enantioseparated by liquid chromatography, all of them were separated by capillary electrokinetic chromatography using single ...

Chiral HPLC Separation of Phosphonothrixin and Phosphonate Derivatives and Electronic Circular Dichroism Characterization of the Isolated Enantiomers

ELECTROPHORESIS, EarlyView.
Natural compound phosphonothrixin's herbicidal activity resides exclusively in its (S)‐enantiomer, yet existing enantioselective syntheses are cumbersome, and direct chiral LC separation is hampered by the compound's high polarity, lack of aromatic groups, and metal chelation–induced peak tailing.
