Diverse reactivity of maleimides in polymer science and beyond

open access: yesPolymer International, Volume 74, Issue 4, Page 296-306, April 2025.
This mini‐review provides a thorough overview of maleimide chemistry, highlighting its diverse reactivity in polymer and materials science applications. Abstract Maleimides are remarkably versatile functional groups, capable of participating in homo‐ and copolymerizations, Diels–Alder and (photo)cycloadditions, Michael additions, and other reactions ...

Block Copolymers From δ‐Tetradecalactone and Lactide: Synthesis, Self‐Assembly, and Ready Biodegradation Test

open access: yesMacromolecular Chemistry and Physics, Volume 227, Issue 3, 16 February 2026.
Various new block copolymers of TDL and LA were produced through sequential polymerization. Some of them were shown to self‐assemble in nonpolar media such as isododecane, with particle formation. Their biodegradability was evaluated under OECD 301F conditions, and they can be slowly biodegraded only for short PLA blocks.

Thiophene Derivatives as Versatile Precursors for (Hetero)Arene and Natural Product Synthesis

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.
Hidden but Powerful: Thiophenes and their saturated analogues have been demonstrated to be versatile C4‐building blocks that can be rapidly applied to natural product synthesis and the construction of functionalized (hetero)arenes. This minireview aims to provide a concise overview of the strategies and implementations of these sulfur‐containing ...

Mesoionic N‐Heterocyclic Olefins, Imines, Thiones, Phosphinidenes and Their Application in Catalysis

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 3, 16 January 2026.
This minireview covers recent advances in the synthesis, reactivity, and metal‐free catalytic uses of mesoionic N‐heterocyclic olefins (mNHOs), imines (mNHIs), thiones (mNHTs), and phosphinidenes (mNHPs). Abstract Transition metal compounds are widely known for their ability to activate small molecules and are excellent catalysts for a wide range of ...

Recent advances in organocatalytic atroposelective reactions

open access: yesBeilstein Journal of Organic Chemistry
Axial chirality is present in a variety of naturally occurring compounds, and is becoming increasingly relevant also in medicine. Many axially chiral compounds are important as catalysts in asymmetric catalysis or have chiroptical properties. This review

Chiral phosphines in nucleophilic organocatalysis

open access: yesBeilstein Journal of Organic Chemistry, 2014
This review discusses the tertiary phosphines possessing various chiral skeletons that have been used in asymmetric nucleophilic organocatalytic reactions, including annulations of allenes, alkynes, and Morita–Baylis–Hillman (MBH) acetates, carbonates ...

Highly Efficient Organocatalytic House‐Meinwald Rearrangement for the Facile Synthesis of Aldehydes: Swift Access to Ibuprofen

open access: yesChemistry – A European Journal, Volume 32, Issue 2, 9 January 2026.
We use readily available epoxides and 0.5 mol% bis(trifluoromethane)sulfonimide (Tf2N) as a catalyst to synthesize a broad range of aldehydes in yields ranging from 89% to 97%. Furthermore, we identified aldehyde dimerization intermediates at lower temperatures and observed their cleavage at 55 °C.
