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 ...

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

Modular Synthesis of α‐Quaternary Pyrrolines by Pyridoxal‐Catalyzed Sequential Reactions With Precise Chirality Relay

open access: yesTransformative Chemistry, EarlyView.
Direct asymmetric α‐C conjugate addition of aminoacetonitrile enabled by carbonyl/iminium double activation, together with subsequent electrophilic functionalization, offers a one‐pot, two‐step modular strategy for synthesizing chiral α‐quaternary pyrrolines with precise chirality relay and high structural diversity.

Selective Chain Scission of L‐Lactide/ε‐Caprolactone Chain Shuttled Copolymers

open access: yesChemSusChem, Volume 19, Issue 21, 12 November 2026.
L‐lactide/ε‐caprolactone chain shuttled multiblock copolymers are composed of PLLA‐rich hard blocks and poly(ε‐caprolactone‐co‐L‐lactide) soft blocks. They can be selectively degraded, notably into PLA oligomers, by organocatalyzed transesterification. This allows not only to determine the block length but also to envision the recycling of the PLA part

Selective N‐Functionalization of Pyrazoles

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 40, 27 October 2026.
This review traces the evolution of regioselective N‐functionalization strategies for pyrazoles, a key class of nitrogen heterocycles widely used in medicinal chemistry. Due to rapid tautomerism, N‐functionalization often lacks selectivity, leading to poor and unpredictable regioisomeric outcomes.
