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.

Synthesis of Naphthoquinones by Pd‐Catalyzed Heck–Matsuda Arylation of Lapachol

European Journal of Organic Chemistry, EarlyView.
Direct Heck–Matsuda arylation of lapachol enables the efficient synthesis of diverse naphthoquinones under homogeneous and heterogeneous palladium catalysis. The methodology features broad substrate scope, gram‐scale applicability, and provides a practical platform for quinone diversification.

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.

The Expanding Role of Diazirines in Synthetic Methodology

European Journal of Organic Chemistry, EarlyView.
Beyond their established role in photoaffinity labeling, diazirines have emerged as versatile reagents in synthetic chemistry. This review highlights their dual reactivity as carbene and nitrogen‐transfer precursors, showcasing mechanistic insights and diverse applications in cyclopropanations, cycloadditions, skeletal editing, amination, heterocycle ...
